@Stefano, many thanks!
From the pulseverbose log it seems like there is a driver problem of not
reporting the hw position correctly.
( 135.836| 0.000) D: [alsa-sink] alsa-sink.c: avail: 336892 (filled: 15876)
( 135.836| 0.000) D: [alsa-sink] alsa-sink.c: 90.00 ms left to play; inc
threshold
So, can you try two different methods of position reporting?
Edit /etc/modprobe.d/alsa-base.conf and add the following line:
options snd-hda-intel position_fix=1
Reboot your computer and see if it works better, and also try this
version:
options snd-hda-intel position_fix=2
Reboot and retry.
I realized I did not start banshee as recommended (and I have not
uploaded the 2nd log).
I upgraded pulseaudio from ppa:diwic/fighting-rewinds, then I performed the
test again, this time following the instructions.
During the test, the sound was indeed broken as expected, with long pauses
Here is the 2nd log (Banshee).
The total playing time is about 3 minutes.

I cannot reproduce the previous behaviour with the special pulseaudio
version. It works better than the one from the distribution (tested with
banshee, vlc and youtube). Skips are hardly noticeable and not frequent.
However, when I played a mp3 file with vlc I heard a crackling sound for

I have the same problem on an Asus eeePC 1101HA, Ubuntu Oneric, kernel
3.0.0-12.20. The 'speaker-test' test plays without stuttering, paplay
stutters. However, this problem also occurs if the processor isn't
loaded, just running the music player at around 10% cpu.
I tried the archwiki solution,
and the gst log

On my Asus eeePC 1101HA, Atom Z520@1.33GHz, Ubuntu 11.10, kernel
3.0.0.12-generic, there are consistent skips as described in previous
posts. I'll try the special PulseAudio as soon as possible.

Hi, is any of you able to replicate the eternal rewind errors with a
special version of PulseAudio, the one in ppa:diwic/fighting-rewinds
(for oneiric), and if so, give me some logs according to

Just to say, I have an eeePC 1101HA 1.33Ghz Atom processor and was

Could you remove the Choppy Sounds fix (that is go back to the

or comes back?

Bugs,
I would happily test it, however I don't know the way. Am I supposed to
apply the patch via bzr as mentioned in the Ubuntu wiki? Sorry but I'm a
bit inexperienced in this, if you have the time to provide a link, or
tell e what to do I can test it. Thanks!

@Lucazade, thanks for the log. It shows that my attempt to solve the
problem was not the right one, as the sleep code was called but it did
not help. So back to the drawing board, basically.
Arun seems to have replicated the issue on his side, and he's a

apt-get source pulseaudio
cd pulseaudio dir
quilt push -a

or use upstream stuff:

I can try it out on atom..
is there a fast way to compile pulseaudio from source?
