Just recently (and I'm not sure why) while playing music from cmus, it will seemingly randomly lock up with dmesg reporting
Code:
i2sbus_wait_for_stop: timed out
. It forces me to restart alsasound and hard kill cmus to get my soundcard back to normal. I'm on a G4 powerbook and I'm using the onyx aoa driver compiled directly into the kernel because I couldn't figure out how to get alsa to load it automatically. Has anyone seen this before?

Thanks!
Jeremy

No, I haven't heard of this with the new aoa driver. Which kernel are you using?

I'm using 2.6.21. I think I may have figured out the problem. It was only happening when I was on battery power, which made me wonder if it had to do with power management. I have laptop mode enabled so that my hard drive spins down after ten seconds of inactivity. I'm thinking that when it's time to advance the sound buffer when I'm playing music, the delay in the hard drive spinning up may be causing an alsa underrun or something. This is only a speculation, however, and I'm not sure if it's really what's happening.
