Description cornel panceac 2007-07-20 11:11:12 EDT
Description of problem:
when the system is _very busy_ , like k3b closing disc, music stops playing and,
on resume, the first second volume is at max (or, much higher, anyway).

Version-Release number of selected component (if applicable):

How reproducible:
write a disc with k3b while listening music

Steps to Reproduce:
Actual results:
music stops, and on resume the start volume is much higher

Expected results:
music doesn't stop, or if it stops, on resume volume remains constant

amd x2 dualcore 5600+ 2800 MHz

this was my home computer.

the same thing happens on my office computer wich is hp, with 512 MiO ram, 3 GHz
intel dual core processor. i'm not at office right now so i can not provide more
info on that machine. anyway, things seemed to improve from fc6 to f7 (the
annoying increase of playback level is shorter maybe, or does not happen that
often anymore(?))

Hello Cornel,

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.


I am CC'ing myself to this bug and will try and assist you in resolving it if I can.

There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?

If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.

Comment 2 cornel panceac 2007-09-20 13:46:46 EDT
it happens with latest kernel too. i have at office two hp's with intel-hda,
i'll test there too, tomorrow. 
thank you.
Comment 3 Christopher Brown 2007-09-20 16:13:07 EDT
Okay, thanks for the info. I've added an ALSA blocker bug which may get this
further review from the relevant maintainers.

Comment 4 cornel panceac 2007-09-22 01:25:24 EDT
it happened today (22nd of september 2007) too, when the system tried to see if
the cd i've put into cddrive is blank or something else.

it also happens when k3b is "closing session".

$ uname -r

$ rpm -qa | grep alsa

Comment 5 cornel panceac 2007-11-14 13:26:07 EST
it is fixed on f8release, sound never stops now. the system (xorg) is still
kinda freezing though. thank you very much.
