Package: alsa-base
Version: 1.0.25+3
Severity: important
Dear Maintainer,
I've been having this problem on CrunchBang 11 "Waldorf" which is based off
Debian Wheezy (I think)
I've had to restart the PC 4 times because of this. Every time I try to listen
to something, at random points it "hiccups" (basically keeps repeating the last
few ms of what I was listening, probably what was on the buffer) and the whole
OS becomes unresponsive, CPU raises at around 95-100% at which point I can't do
anything but turn the PC off. The GUI (TTY7) becomes very unresponsive (for
example when I move a window from one place to another, it slowly creeps to the
destination. Also TTYs 1-6 are unusuable as they get flooded with this error:
[XXXXX.XXXXXX] cmipci: invalid PCM pointer: 0xffff
X = random number that keeps increasing.
I was mainly listening to music over VLC also tried cmus. On the 3rd and 4th
time after restarting I tried I changing the output module from pulse (knowing
it can be problematic at times) to alsa but that didn't fix anything.
* What led up to the situation?
Nothing in particular, this has been happening since I installed the distro. It
even behaved this way in the LiveCD session.
* What exactly did you do (or not do) that was effective (or
ineffective)?
I tried to add the unstable repositories in the hope that a more recent version
of ALSA might have fixed this bug but it was not the case.
* What was the outcome of this action?
At first, since it took some time for the error/bug to show up, I thought
updating fixed everything, but after 1-2 hours of listening to music the
problem resurfaced.
* What outcome did you expect instead?
Sound to work continiously without this error popping up and rendering my PC
completely unusuable.
I'm not sure if this is a debian-specific bug as I haven't exited the Debian-
sphere, but if this isn't related to Debian itself, please prompt me to send
this to ALSA instead.
Thank you in advance.
