[Touch-packages] [Bug 996906]
Some more info. On my new laptop that also has a VIA sound chipset I managed to greatly leverage the problem by installing the low-latency Ubuntu kernel. I have Ubuntu MATE 14.04 on it so it was effortless. Unfortunately, for (presumably) performance reasons it doesn't have CONFIG_SND_PCM_XRUN_DEBUG enabled so I can't see if it also misses interrupts. However, on the default stock kernel which has this option it misses interrupts indeed. I tried various position_fix and enable_msi values and nothing helped. I had underruns in the log while doing usual things like opening sites, now on the low-latency kernel it's all good even on PA's timer-based scheduling. I can only guess but it could be because the CPU has only two cores and sometimes it can't schedule an interrupt in time. The low-latency kernel has 1000 Hz timer compared to 250 Hz in the default one. It also has various NO_HZ_* options enabled. I'll try two options on Monday with my own kernel for Debian: one would be using the BFS scheduler and another one will feature CONFIG_NO_HZ_FULL_ALL and alike options which are disabled when BFS is used. I'll check if either of them will help with the missed interrupts. The problem as I see it is that my work PC and this laptop isn't powerful enough to server IRQs in time. They both have VIA sound although a bit different models and 2 core CPUs. My home PC has 4 cores that are also more powerful. I tried to output some sound via PA to its Realtek ALC889 card and enabled xrun_debug. There were no messages about lost interrupts and I'm using the same kernel that's used on the work PC. So the different behavior is either because of different codecs/chipsets or CPUs. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/996906 Title: periodic audio skips with Intel HDA Status in PulseAudio sound server: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: When running PulseAudio, if I'm playing music via any source (Exaile, Totem, Flash in Firefox or Chromium, VLC, etc.) every few minutes the audio will skip once or twice. top doesn't show any process eating CPU any more when it happens. dmesg doesn't show anything.

[Touch-packages] [Bug 996906]
So I've done some research. This article describes the timer model and how ALSA works in regards of periods/fragments and software/hardware buffers: http://0pointer.de/blog/projects/pulse-glitch-free.html According to the article, PA works in two modes, with tsched=0 it's the old IRQ-driven mode as ALSA does and it heavily relies to the fragments number and size. Hence it gets ALSA underruns if the app is too slow to fill the buffer. It happens to my work PC sometime because it isn't too fast (model name: Intel(R) Pentium(R) CPU G620 @ 2.60GHz) and I mostly listen to music in Chrome (HTML5 audio). Chrome has the latency of ~65 ms now. It's quite feasible that some program would occupy the CPU for this much time so I'd have a skip/underrun. In case of tsched=0 there's nothing we can do as period/buffer size is set up on startup and basically can't be changed in runtime. When tsched=1 or not specified (defaults to 1) PA sets up an ALSA buffer of 2 seconds long with two periods of 1 second each. This way it doesn't underrun in ALSA but rather underruns in PA itself. This code is responsible for tweaking the watermark and latency: https://github.com/pulseaudio/pulseaudio/blob/master/src/modules/alsa /alsa-sink.c#L326 The problem here is that watermark can go in both directions, up and down, while latency can only grow until the sink is reset (recreated). This actually means that if some particular program has chosen too little latency and had several underruns because of that, THE WHOLE LOT OF OTHER PROGRAMS now will suffer bad latency as well! And there's no other way to lower it back other than restarting PA itself together with all its clients or when PA gets unsuspended ( https://github.com/pulseaudio/pulseaudio/blob/master/src/modules/alsa /alsa-sink.c#L1021 ). I haven't found a way to setup a default minimal latency so that if I know that my system isn't capable to deliver 4 ms, I can set it to 16 instead of having 0.5 ms and several underruns just to let PA get to that latency by itself. It seems to me that this minimal latency is just hardcoded ( https://github.com/pulseaudio/pulseaudio/blob/master/src/pulsecore/sink.c#L54 ) and there are no tools to call pa_sink_set_latency_range ( https://github.com/pulseaudio/pulseaudio/blob/master/src/pulsecore/sink.c#L3091 ) And also, I repeat, launching pavucontrol for the first time and sometimes pacmd list-sinks causes stuttering on my work system (works ok at home but there I have i7-2600 and PCI SB Live 7.1). I don't know how and why but they seem to block PA somewhere so that Chrome can't sink its audio to it in time and hence we get an underrun, latency increase and the bad mood. I dunno, maybe I have to file this pavucontrol bug separately. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/996906 Title: periodic audio skips with Intel HDA Status in PulseAudio sound server: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: When running PulseAudio, if I'm playing music via any source (Exaile, Totem, Flash in Firefox or Chromium, VLC, etc.) every few minutes the audio will skip once or twice. top doesn't show any process eating CPU any more when it happens. dmesg doesn't show anything.

0.5 ms is just what PA reports as the minimal latency. I don't need it to be this small, I just don't want it to grow up to 100 ms without the possibility to automatically drop it back to normal. I suppose it's not possible to make PA work with fragments as ALSA does. As I understand from the Lennart's article, the latency in ALSA is the size of period ±something. For PA it's the size of fragment * number of fragments as it reports this as the minimal latency in pacmd list-sinks. It's also very noticeable when you use realtime apps like LMMS or games. However, it's not true for dmix.

So I've bought a laptop with VIA sound as well and it also have skips/stutters. I worked around it on both systems with these steps: 1) in /etc/pulse/default.pa added tsched=0: load-module module-udev-detect tsched=0 2) to reduce latency set in /etc/pulse/daemon.conf: default-fragments = 4 default-fragment-size-msec = 1 The final latency is a product of these numbers, 1*4 == 4 ms which is acceptable. The number of fragments should be at least 2 so the least latency possible is 2*1 == 2 ms. I don't know if there's a real difference between 4 fragments of 1 ms each or 2 fragments of 2 ms each. Try some experimenting. At least now I don't have latency increase and sound doesn't skip on pavucontrol launch, though it still skips on LMMS launch. Based on the comments' content and timestamps here, it looks to me that no one in PA team really cares about HDA Intel cards which are the most popular cards. And if PA performs badly with them out of the box it hurts PA's face, no matter who's to blame actually. Plus, pure ALSA works fine or doesn't work at all, usually. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/996906 Title: periodic audio skips with Intel HDA Status in PulseAudio sound server: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: When running PulseAudio, if I'm playing music via any source (Exaile, Totem, Flash in Firefox or Chromium, VLC, etc.) every few minutes the audio will skip once or twice. top doesn't show any process eating CPU any more when it happens. dmesg doesn't show anything.

I don't know if it's related but there's no error messages in dmesg if I run PA without tsched=0. Though in this case skips are pretty audible and the fragment size and their number aren't respected. Even worse, latency grows over time with each skip and becomes unbearable. With tsched=0 I can at least get it fixed. I also have skips when PC is under load (Java compiling, tabs reloading at the same time etc.). PA says it's working in realtime mode so these userland processes should not interfere. It reports in its log that it's the ALSA underrun, not the application's one.

Created attachment 115003 Syslog with debug info Here's my full syslog. First I started PA with: default-fragments = 9 default-fragment-size-msec = 2 So the buffer was 800 frames, I couldn't get it to be 768 to have exactly 16 ms latency. So it was 18 ms. I had no errors in dmesg while using value of 11 for xrun_debug. Then I set params to 4 fragments of 1 ms each and had errors. enable_msi=0 didn't help IIRC, neither did position_fix.

I was too fast coming to conclusions. ALSA plugin in LMMS still croaks after PA worked several hours and gained latency of 36.00ms currently. It may go down if I disconnect all its clients but I'm listening to music all the day while working so it's not an option. Underruns happen more often if LMMS is just working in the background not doing anything. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/996906 Title: periodic audio skips with Intel HDA Status in PulseAudio sound server: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: When running PulseAudio, if I'm playing music via any source (Exaile, Totem, Flash in Firefox or Chromium, VLC, etc.) every few minutes the audio will skip once or twice. top doesn't show any process eating CPU any more when it happens. dmesg doesn't show anything.

It turned out that garbled sound in LMMS with alsa output was because of options snd-hda-intel position_fix=1 I used in module options. Tried to fix this skips but it didn't work. After removing this option and reloading the snd_hda_intel module, LMMS sounds much better with alsa output but that clicks are still audible sometimes. PA also seems to lower latency after an underrun occures as I see in the log latency increasing like 1-2-4-8-4-8. The lowest latency I've got with paplay is 8 msec, any less produces clicks or garbled sound. aplay -D hw:0,0 -v --buffer-size=1024 /usr/share/sounds/alsa/Front_Center.wav Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono aplay: set_params:1239: Channels count non available However, device default works fine.

LMMS uses 64 frames, 1.5 ms but actually it has latency of 30-35 ms as pacmd list-sink-inputs says. Setting its output to ALSA results in extremely garbled sound, the only two options that actually produce reasonable sound is PulseAudio (bad latency) and SDL. Actually, latency isn't that bad if only PA doesn't increase it internally for every client. I've got a decent CPU here, G620 @ 2.6 GHz so I may understand skipping on high CPU load, BUT PulseAudio has very high realtime priority (15) and if I use pure ALSA there are no skips. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/996906 Title: periodic audio skips with Intel HDA Status in PulseAudio sound server: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: When running PulseAudio, if I'm playing music via any source (Exaile, Totem, Flash in Firefox or Chromium, VLC, etc.) every few minutes the audio will skip once or twice. top doesn't show any process eating CPU any more when it happens. dmesg doesn't show anything.

Created attachment 113034 Underruns in the log Same with VIA VT1708S. When I start pavucontrol it skips hardly and almost stops sometimes. Because of that latency increases and may get up to 80 ms which is unacceptable as PulseAudio's goal is to provide low latency audio. Of course, it doesn't happen with pure ALSA. I already set all priorities to the maximum, doesn't seem to help.

Created attachment 113083 Underruns with prealloc=2048 I was able to leverage the Underrun! issue by setting prealloc to 2048 in kernel options (recompiled it). It can also be achieved via echo 2048 /proc/asound/card0/pcm0p/sub0/prealloc without recompiling. Wonder why 64 is still default in Debian/Ubuntu. So it doesn't change the latency/watermark now this hard. However, I still get Underrun! after launching LMMS. It also spams the syslog with Feb 03 08:58:35 work pulseaudio[1895]: Pool full And there are still clicks in the playback from time to time. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/996906 Title: periodic audio skips with Intel HDA Status in PulseAudio sound server: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: When running PulseAudio, if I'm playing music via any source (Exaile, Totem, Flash in Firefox or Chromium, VLC, etc.) every few minutes the audio will skip once or twice. top doesn't show any process eating CPU any more when it happens. dmesg doesn't show anything.

Interesting. I've converted that file to 44100 Hz and now it reveals a strange behavior. When I play it with buffer size of 64 it sounds like the pitch is lower than it should be (even if it doesn't overrun though it does from time to time).

This command doesn't work, it says aplay: set_params:1239: Channels count non available. The -D default:CARD=CA0106 variant works and it does not overrun. I only had overruns on recording (at least, explicit). That said, I've made a huge improvement in my system, I compiled a pf- kernel and set CONFIG_PREEMPT=y, CONFIG_HZ_1000=y and CONFIG_HZ=1000. The default Debian kernel is on 250 Hz and is not preemptible. Now that my kernel supports preemption I (crossing fingers) don't have ALSA over- and underruns anymore. They were quite sudden and audible as clicks/gaps.

BTW, my mic is connected to the blue jack, not the usual pink one. This is the only configuration I've found to be working, others result in noise or silence. The mic is a bit more quiet (not _almost silent_ as if it's connected to a Line-In jack, just not comfortable enough) than it was on the ALC889 internal card so I had to increase the volume via software means.

(In reply to Raymond from comment #8) how did you run the program ? the program is hardcoded to use 44100Hz , it should run continously without any error if fillrate is equal to period size if sound card can report hw_ptr with better grannularity, the program can still run continously when fillrate is smaller than period size (e.g. dma brust size ) I did: gcc alsa-time-test.c -lasound ./a.out That's all. What exactly should I do now and what information do you need? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1315212 Title: [CA0106 - CA0106, playback] Playback problem - Surround dies, no valid output Status in ALSA driver: Confirmed Status in alsa-driver package in Ubuntu: Incomplete Bug description: This is tested against a Creative Labs Sounblaster live!
