[Bug 428619] Re: pulseaudio crackle/distortion with cs46xx on latest update
I do not know much about ubuntu/linux, but I have been trying things blindly for awhile and will only add what has not already been said. I get huge variations in the quality of sound when I adjust the hardware profile under sound preferences. The changes range from no sound, to very tinny sound, to crashing audio on the system, to crackling, to machine gun, and on. All with different profiles. Today, after updating alsa and messing with the profiles some more, I managed to play one song on vlc with absolutely no audio problems. When I closed the audio player and played a different song, it was back to the regular problems and I haven't been able to replicate a good play again. I don't know what that means, but it seems strange as hell. hope that helps someone who knows whats going on. -- pulseaudio crackle/distortion with cs46xx on latest update https://bugs.launchpad.net/bugs/428619 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

THis patch is not in the stable queue, so I am hesitant to pull it into the package for maverick, and this is probably not a patch that would qualify for an SRU.

Same problem here...Turtle Beach Santa Cruz PCI with CS4630 chipset in a Dell Optiplex 620. This card was working wonderfully in 9.04. I skipped the 9.10 upgrade after reading that support for this card was broken. I had to upgrade to 10.04 LTS to work on another project, and as mentioned above, the card is broken in 10.04 LTS. There are periods (10-15 seconds) of working sound, followed by motorboating for 5-10 seconds followed by working sound. When the sound is working, there is crackling. I played around with settings and tried a number of the fixes suggested in other forums and blogs, but nothing has worked so far. The card works wonderfully in Windows XP. This is a nice sound card that serves me well, and I really dislike throwing away working hardware because of buggy software support.

[Bug 428619] Re: pulseaudio crackle/distortion with cs46xx on latest update
This bug is listed as a duplicate of a different bug report that more accurately described the symptoms that I am seeing. In my machines. What I see is total sound failure (apart from a few intermittent clicks at boot time) on machines that worked fine with 9.04. That includes three machines from two different makers, Lenovo and Sharp. Actually, it might be three makers, since one of the machines is old enough that it is probably an IBM. I've tried upgrades, clean installs, running live from the CD, and also from VMware Player. Most of the machines are fairly new. Excuse me, but this is a massive failure. Ubuntu needs to do much better regression testing. I like Ubuntu, but it is no longer an OS that I can recommend to anyone. Off topic, but I think the main problem with Ubuntu is now the broken economic model that is driving the adoption of features without adequate testing, while at the same time leaving old bugs open, sometimes for years... (I've already suggested an alternative funding mechanism, but never detected any interest at the Ubuntu end...) Unless these massive show-stopping problems are fixed, Ubuntu is going to fail. -- pulseaudio crackle/distortion with cs46xx on latest update https://bugs.launchpad.net/bugs/428619 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 428619] Re: pulseaudio crackle/distortion with cs46xx on latest update
Okay. Here are the specific symptoms (file attached): Often, nothing noticed until I start a music player (any will do). Ubuntu bongos play normally when I log in. I start a music player, choose a song, press play, and often, a song will start to play (sometimes: silence- about 20% of the time). If the volume is too high or low, I slide the slider on either the player or the master volume and every other detent the music will loop- about fifteen to twenty times per second, until I move the volume to the NEXT detent and either the song goes silent or returns to normal playing- but at a higher or lower volume. So attached is the troubleshooting file. I cannot get this behavior without pulseaudio running. I also couldn't get this behavior in Debian, normal (read: ancient) install. If there's anything to add- I can't get this laptop (IBM A20m) to correctly play with Speedstep governors. ACPI (and acpi-ibm) are working very well: lmsensors, fine- but there's no cpu speed indicated in the /sys filesystem. Not that it means anything, of course, but I'm just tryin' to be complete with systemic problems which might affect pulseaudio.

1. Arch Linux is stuck in Pulseaudio 0.9.15 because of this. 2. CS46xx is buggy as hell. It is possible, but difficult, to trigger the same bug with plain ALSA. Also, Pulseaudio with ts_sched=1 is unusable with CS46xx. Audio streams lose their synchronization, and the only way to play audio reliably with that is playing with PAVuControl always enabled. Also, I read somewhere in the ALSA mailing lists that the timing mechanism for the CS46xx driver is unique and buggy.

I have my doubts that this is a pulseaudio problem. If I kill pulseaudio and play sound with alsaplayer, I get exactly the same effect. Also, when I run pulseaudio manually, I see things like this: E: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! E: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_cs46xx'. Please report this issue to the ALSA developers.

Looking at the differences between svolume_sse.c from pulseaudio 0.9.16 and the current one I noticed that those changes are only cosmetical - only a comment has changed. It does not make sense to try to patch that... But you can of course try the patch I posted in #19 and see if that works for you. It is quite simple really. Assuming you... - keep your sources in /usr/src - downloaded the patch to your home directory - have not built pulseaudio before so there are no pulseaudio*.deb or libpulse*.deb packages in /usr/src ...it goes something like this: (first get the build dependencies:) sudo apt-get build-dep pulseaudio (now get the source:) cd /usr/src apt-get source pulseaudio (patch the source:) (cd whatever directory the source was installed to, currently pulseaudio-0.9.18 so...) cd pulseaudio-0.9.18 patch -p1 ~/revert_svolume_mmx_to_known_good_version.patch (build the binary packages:) fakeroot dpkg-buildpackage -b (install pulseaudio and libpulse:) (while still in the pulseaudio source directory, directly after the build has finished:) sudo dpkg -i ../libpulse0_*.deb ../pulseaudio_*.deb As to how to test the new build depends on how you use it. If you run a sound-generating package like mplayer or totem it should be sufficient to kill any running pulseaudio daemon with: pulseaudio -k It should autostart the next time you start any sound-generating program... unless you have autospawn=no in your personal pulseaudio config of course... in that case you need to start it manually. If you run some sound-generating daemon like mpd you may need to restart that to make sure it starts a fresh copy of pulseaudio.

After modifying that incantation a bit by adding PULSE_NO_SIMD=1 to the mpd init script as mpd starts its own version of pulseaudio the noise dissappeared... in other words the recent problems with distorted sound ARE caused by the SSE-optimized code... There are very few changes to the actual assembler code in svolume_sse.c, I'll try a version of current pulseaudio with these changes reverted to see if that makes a difference... be right back... -- pulseaudio crackle/distortion with cs46xx on latest update https://bugs.launchpad.net/bugs/428619 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Another observation: the volume control on a client (in my case mpd) does not actually change the volume. There are three states: volume maxed, sound OK volume between maxed and minimum, sound distorted at full volume volume minimized, no sound -- pulseaudio crackle/distortion with cs46xx on latest update https://bugs.launchpad.net/bugs/428619 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 428619] Re: pulseaudio crackle/distortion with cs46xx on latest update
OK, I found it. The problem - in my case at least - lies in svolume_mmx.c (not svolume_sse.c). Reverting that file back to the previous version gets rid of the problem.

[Bug 428619] Re: pulseaudio crackle/distortion with cs46xx on latest update
I should add that I run pulseaudio on a Thinkpad T23 with a Pentium III-m which does NOT support SSE2. As I do not have any systems available which do support SSE2 I can not test the validity of svolume_sse.c (which actually contains SSE2 code, not SSE...). Someone else, like the original bug reporter (who seems to run a Pentium 4 which does support SSE2) should try to revert svolume_sse.c back to a previous version and test with that. -- pulseaudio crackle/distortion with cs46xx on latest update https://bugs.launchpad.net/bugs/428619 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Same problem here on different hardware running latest pulseaudio from ubuntu-audio-dev. Symptoms are the same: sound is sort of allright when the volume client is maxed, anything below that sounds from bad to worse.
