Hi,
We use Debian Wheezy (3.2.0-4-amd64) with Digigram Lola 881.

In our application we use FMOD library and we get the below error.
While audio is playing, the sound is lost and player continued reading audio file but very very fast.

The player that we developed runs almost 20 hours a day. Interestingly, we had this problem:
Mon Sep 23 21:26 (error time)
Wed Sep 18 16:10 (reboot system for another reason)

Sun Sep 15 10:48 (error time)
Tue Sep 10 08:22 (error time)
Thu Sep 5 16:01 (install date)

As it is seen, we have this problem almost 5 days after system boot.

What may be the cause of this problem? Memory?

the message you pasted seems likely to be relevant:

Sep 23 21:13:07 ank-yay7-30 pulseaudio[25029]: [alsa-sink] alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write!

Sep 23 21:13:07 ank-yay7-30 pulseaudio[25029]: [alsa-sink] alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_lola'. Please report this issue to the ALSA developers.

Sep 23 21:13:07 ank-yay7-30 pulseaudio[25029]: [alsa-sink] alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail."

why not start there?
