Public bug reported:
I'm on Karmic alpha 4, 64-bit on a second-generation MacBook.
Often when I play sound I cannot hear the sound being played. (ie the
speakers do not produce an actual sound, despite the application
attempting to play a sound). If I use Pulse Audio Volume Meter to
monitor volume levels, the bars move, clearly indicating that it thinks
it's playing sound. It recognizes my sound hardware as IEC 958.
Counter-Strike sound under wine works perfectly. However, I never hear
a login sound, XChat does not produce sound effects, and if I attempt to
play a .wav file using "play" from command line, I hear nothing.
My speakers work fine on OS X and, like I said, with occasional Ubuntu
apps.
My sound works perfectly with Karmic alpha 3 out of the box and also
with Jaunty, as well as Fedora 11. My sound broke after some of the
pulseaudio updates between alpha 3 and alpha 4. (According to IRC, I'm
not the only one).
