As mentioned in this thread, I had severe audio issues in Frodo 12.0. In summary, I would have sound in the menus, but when playing a video it would stutter and audio would not work. After pressing stop sound would also be gone in the menus. As you can see from the thread I linked, I managed to get audio working by creating an /etc/asound.conf file. This solution worked pretty well, but from time to time - especially when attempting to stream some HD content - audio would cut out as before. But this happened completely randomly, and rarely.

After upgrading to 12.0 from 12.1 I again experience audio issues. Now, most of the time audio crashes as before when playing a video, even though audio worked in the menus until pressing play. Strangely, some videos do play from time to time, as you can see from the below-mentioned debug log file. However, audio may then just as well crash on playing another video (as evidenced by the same debug log file).

This happens both with the mentioned /etc/asound.conf file present, and with all /etc/asound.conf files and .asoundrc files removed. Pulseaudio is not installed (i am using XBMCbuntu as my underlying distro). Sound hardware in XBMC is set to analog audio, Intel HDA.

I am really puzzled by this, especially since the changelog for 12.1 reads as follows:

Quote:XBMC no longer hogs audio for Linux and on resume audio will continue to work in Linux

I interpreted this as if the audio bugs/issues I struggled with previously were finally fixed. However, that does not seem to be the case...

Thanks in advance for any help and/or suggestions!

You clearly see in the xbmc.log that it comes up _before_ your pulseaudio server is up - after shortly not using the audio device, pulse grabs it over and keeps it - no idea what I should do about it?

sudo apt-get remove --purge pulseaudio libasound2-plugins
sudo reboot

And crashlog would be nice :-)

Hmm, pulseaudio is not installed, but I ran your command anyhow. The output was as follows:

Code:
sudo apt-get remove --purge pulseaudio libasound2-plugins

Removing libasound2-plugins ...

I then rebooted.

However, this did not solve my issue. As you can see from this new log, the problem persists: http://xbmclogs.com/show.php?id=6963 Also: I have no crashlog, as XBMC itself does not crash. Only the audio disappears. Sorry for using a bit imprecise language in this relation in my first post...

Does anyone have further suggestions as for what I may try?

Jep - it cannot initialize the sink, can you try the following one: m_displayNameExtra: ALC892 Analog instead of the default?

I attempted setting "ACL892 (Analog)" as the default audio device and rebooted. However, this did not make any difference.

Here is the latest log: http://xbmclogs.com/show.php?id=7207

Does one of the following help:

Code:
<audio>

  <resample>48000</resample>

  <streamsilence>1</streamsilence>

</audio>

I think it is the samplerate, that your device is extremely pick of - the code part where it fails is this one:

Code:
if (!OpenPCMDevice(device, AESParams, m_channelLayout.Count(), &m_pcm, config, format.m_sampleRate == (unsigned int) dmixRate && !m_passthrough))

I really wonder why this happens - could you make screenshot of your audio settings?

This:

Code:
<audio>

  <resample>48000</resample>

</audio>

Seems to have done the trick! At least it has worked for a few minutes now. Thanks so much for the prompt responses and insightful comments. I think I'll make a donation to the XBMC project as a way of paying back. Afterall, I've been using XBMC for free for years already ;-)

Btw, the screenshot of my audiosettings (in norwegian, but I hope it is okay) is available here, if you are still interested: http://bildr.no/view/1424370

Thanks. Have fun using xbmc :-)
