Re: [pulseaudio-discuss] Problems with mplayer in Ubuntu 10.04
Hello Colin and Daniel! I just found the following Ubuntu PPA repo: https://launchpad.net/~scottritchie/+archive/ppa which includes the latest release of OpenAL. I installed it and now mplayer works fine. Yay! Daniel: *Please* backport it to Lucid (lucid-updates or lucid-backport). I am sure it breaks on many systems. Colin: If you can break the freeze, perhaps this is the moment. The latest release of OpenAL solves the problems I had. Thank you all!

Re: [pulseaudio-discuss] Problems with mplayer in Ubuntu 10.04
Hello Dan! Thank you for your detailed answer. It is an unfortunate situation, but I do agree, it's not Ubuntu's fault per-se, it is certainly understandable/acceptable. Nonetheless, this is Ubuntu 10.04 LTS and I will, perhaps, not upgrade to Maverick. Perhaps I will wait for the next LTS release. Could the new/fixed release of OpenAL be back-ported to Lucid? I do not want to stick two years with broken mplayer/wine audio, nor do I want to make my own horrible home-patches to the Ubuntu installation - I mean I wouldn't like to compile my own openal and/or mplayer packages. That is the only thing I ask: lucid-backport ... or an Ubuntu PPA from where me and many other users can get it. If this is possible, please let me know, so I can test it. Thank you again Daniel.

[pulseaudio-discuss] Problems with mplayer in Ubuntu 10.04
Hello everyone! I have Ubuntu 10.04 (AMD64), cleanly installed on a new system I bought, an Intel Pentium Dual Core E6500 with an Asrock P5B-DE mother board, 3 GB of DDR2 memory. This mother board comes with an HDA Intel onboard audio card, HDA Intel, that has the Via VT1708S codec. This onboard audio card does not have the ability to do hardware mixing as it seems. I also have a TV tuner which is connected via the line-in port. Even if capturing is enabled in alsamixer, for the linein, I cannot hear any sound (no hw mixing). This is why I workaround the issue with the loopback-module provided by PulseAudio. Everything else seems to work fine, PulseAudio mixes all audio streams nicely. The problem is with mplayer. I cannot play *any* sound with it, and worse, it causes PulseAudio to go bonkers. Once I start mplayer, I cannot hear any sound, from any application. I tested mplayer from the default Ubuntu repositories [1] and a much newer build from the RVM Ubuntu PPA repository [2] (the author of SMPlayer, if I am not mistaken). Both behave quite much the same. Usage scenario #1: 1. No sounds playing. 2. Start mplayer -ao pulse video_with_audio.avi. Expected result: video plays together with audio. Actual result: video plays without any audible sound. More info: if I try to play other sounds with other apps (say vlc or gnome system sounds), they all seem to work fine, but I can no longer hear them, just like with mplayer. Mplayer seems to work fine - no errors, but I cannot hear anything. pavucontrol shows the mplayer (and other audio streams). The VU meter indicates proper audio stream activity, all is fine. No volume is muted/low, no stream is suspended (pacmd ls), nothing shows wrong. Semi-workarounds: - pulseaudio --kill. This restarts the PulseAudio system and then it works fine again. - change card profile (say from stereo to 7.1 and back). This makes PulseAudio output sound again. If I do this while mplayer plays the video file, I can hear its own audio stream fine. This means that only the initialization of mplayer makes pulseaudio go bonkers. Usage scenario #2: 1. Start vlc video_with_audio.avi. (making sure it is configured to use PulseAudio output). Sound plays fine. 2. Start mplayer -ao pulse another_video_with_audio.avi. Expected result: I can see both videos playing and I can hear both audio streams mixed. Actual result: I can see both videos playing, but no sound. Even the sound from vlc goes mute. Again, there are no indications of errors from any of the players, nor from pacmd ls, nor from pavucontrol. I can see both audio streams playing fine. Same semi-workarounds apply. Usage scenario #3: 1. Start mplayer -ao alsa/jack/etc. It's all the same as -ao pulse, with some notable differences: a) mplayer from default Ubuntu repos allows the use of -ao esd, which no longer breaks PulseAudio and the audio stream *almost* plays fine. It does not play fine, because after a few random seconds it stops - I can no longer hear sound. If I seek within the file with mplayer, then it resets some buffers and I can hear the audio stream again, and so on. At least it doesn't break PA. ;) b) mplayer from RVM Ubuntu PPA ... behaves with -ao esd as it does with -ao pulse. However, -ao oss works fine. I can hear the audio stream with no problems. Nonetheless, -ao oss manages to take over PulseAudio and that means any sounds coming from PulseAudio are not heard by me. Once I stop mplayer the situation does not 'recover', I need to kill pulseaudio or change the card profile back and forth. Usage scenario #4: 1. Start mplayer. No -ao pulse, no video/audio file, just so we can see its command line help. Expected result: I get the mplayer help and that there's no sound output, and that it does not affect PulseAudio. Actual result: mplayer somehow manages to break PulseAudio once again, irrespective of -ao pulse, irrespective of giving it any video/audio file to play. WTF? moment here. Debugging the problem: 1. Starting mplayer with -msglevel all=9 shows no errors at all. 2. pacmd ls and other lists/infos from pacmd do not show errors/problems. 3. pacmd set-log-level 4 does, finally, show errors in /var/log/syslog. The gist of the problem lies in: pulseaudio[8713]: client.c: Created 30 Native client (UNIX socket client) pulseaudio[8713]: client.c: Freed 30 Native client (UNIX socket client) pulseaudio[8713]: protocol-native.c: Connection died. pulseaudio[8713]: module-udev-detect.c: /dev/snd/controlC0 is accessible: yes pulseaudio[8713]: last message repeated 10 times pulseaudio[8713]: client.c: Created 31 Native client (UNIX socket client) pulseaudio[8713]: protocol-native.c: Protocol version: remote 16, local 16 pulseaudio[8713]: protocol-native.c: Got credentials: uid=1000 gid=1000 success=1 pulseaudio[8713]: protocol-native.c: SHM possible: yes pulseaudio[8713]: protocol-native.c: Negotiated SHM: yes pulseaudio[8713]: module-augment-properties.c: Looking for .desktop file for

Well mplayer -ao oss will bypass pulse completely and, as you say, basically hog the sound h/w. You can theoretically use: padsp mplayer -ao oss and that should redirect oss output via PA too, but this may or may not work overly reliably (aka YMMV). The result of calling padsp mplayer -ao oss is the same: 1. I can see now mplayer with OSS emulation in pavucontrol, vu meter is fine, audio stream activity, etc. 2. I hear no sound, pulseaudio is borked/hogged. 3. Changing the card profile back and forth does make it work, while mplayer is running. So, no luck.

The problem does not seem to be related with mine - the mplayer release in Ubuntu repos is much older and I get no errors from MPlayer. In the early days I did get this warning: bt_audio_service_open: connect() failed: Connection refused (111) ... but that was simply because of the bluez-alsa package. I found online info that removing the package solves this minor issue. I removed the package and, indeed, I no longer see the warning. (I do not use bluetooth, so the package removal does not affect my usage.) Other ALSA-based applications play sounds fine, for example Flash Player 10.0.

Perhaps you can test with a fresh user account?
