Description Richard Schwarting 2007-12-09 20:46:26 UTC
Description of problem:
I updated my girlfriend's MacBook to-day (the first time in a few weeks), and
now the audio has some static in it.  I am not sure whether this is a problem
with alsa or pulseaudio.  

I was used to static back when I could adjust PCM and Master volume settings on
my own laptop, and the problem was usually PCM being set above 72.  I no longer
have access to these settings, it seems, due to pulseaudio.  

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

How reproducible:

Steps to Reproduce:
1. play some music (eg. ogg123 beethoven.ogg :)
Actual results:
* hear music, but with static (as though PCM is too high)
* music is also quiet (even when volume from gnome-volume-control is set to max)

Expected results:
* hear music at an appropriate volume and without static

Additional info:
I am wondering whether this computer is no longer detecting its soundcard correctly.

How did you access the sound card setting?
alsamixer -c 0?
How does pulseaudio affect that?

Comment 3 Lennart Poettering 2008-03-28 19:53:56 UTC
alsamixer -c0 should fix your problem.

Comment 4 Craig Kelley 2008-05-20 16:20:40 UTC
I changed my audio preferences to go back to OSS, and it fixed the problem.  The
default ALSA device shouldn't be pulseaudio if it is so broken.
