    Losing audio intermittently

    I'm using Ubuntu 13.04 and recently, I've been experiencing some strange sound loses and it's not clear when this happens. I could be playing a game or playing some music. Suddenly, I will lose audio and nothing I do save for a reboot will restore the sound.

    http://www.alsa-project.org/db/?f=52...e925cdab7dd922

    I've tried restarting pulseaudio. I've also tried removing .pulse* and restarting pulse. I've also tried alsa force-reload but it seems that nothing solves this issue.

    Can someone help me because I'm at a loss at what is wrong. I see no error entries in /var/log/syslog.

    FYI. My sound is via HDMI audio.

    No good. I still lose sound. I started a game and let it run on its own and the sound goes after a while. Then I have no sound permanently in my desktop.

    Someone, please help.

    Maybe I've been away too long, but what is this:
    Code:
    !!ALSA Version
    !!------------
    Driver version:     k3.8.0-30-generic
    Library version:    1.0.25
    Utilities version:  1.0.25
    Mine looks like this:
    Code:
    !!ALSA Version
    !!------------
    Driver version:     1.0.24
    Library version:    1.0.25
    Utilities version:  1.0.25

    It may have been from the experimental intel hd alsa stuff (https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS)? I think. I have no idea what it is otherwise. I'm hoping someone can help me. I lose sound when I play specific games like Red Orchestra or Trine 2.

    As a minor bump... I'm now in Ubuntu 13.10 with the same problem when running Trine 2.

    I'm uncertain what to do at this point.

    I have tried doing sudo alsa force-reload. This is the output I get.

    Code:
    $ sudo alsa force-reload

    Re: Losing audio intermittently

    I found this in the syslog.

    Code:
    Apr 24 12:03:39 pulseaudio[2135]: [alsa-sink-ALC888 Digital] alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write!
    Apr 24 12:03:39 pulseaudio[2135]: [alsa-sink-ALC888 Digital] alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers.
    Apr 24 12:03:39 pulseaudio[2135]: [alsa-sink-ALC888 Digital] alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.
    Apr 24 12:06:12 kernel: [  504.000596] hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.
    Attempted to get rid of the bdl_pos_adj log entry with this in /etc/modprobe.d/alsa-base.conf
    Code:
    options snd-hda-intel model=auto enable_msi=1 bdl_pos_adj=1
    It did not solve the audio issues nor remove the log entry.
