Red Hat Bugzilla – Bug 417481
audio has static, is quiet, since some update
Last modified: 2008-05-20 12:20:40 EDT
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):
Steps to Reproduce:
1. play some music (eg. ogg123 beethoven.ogg :)
* 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)
* hear music at an appropriate volume and without static
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?
alsamixer -c0 should fix your problem.
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.
