Bug Description
This is a very strange problem. Sounds on my powerbook get quieter the longer
they play, until they are not audible anymore even at max volume. This process
starts again for each new sound. So for short sounds everything is mostly ok,
but for longer sounds (such as the login tune), only the first part can be
heard, and then it fades into nothing. I've filed this against alsa-driver,
because I recompiled 2.6.10 with alsa support build in along with pmac_dma, and
oss_api built in, and the problem goes away. However I am very tentative about
that being the actual problem. With that configuration the alsa init script
fails when calling amixer, so the problem could very well be in the large volume
of code in the alsa init script.
Sorry, forgot machine config
