Re: [Alsa-user] getting clean audio from audigy nx 2: two choices... need advice

[Renick B. <re...@gm...>]

I've downloaded 1.0.9b and installed it according to the instructions
in INSTALL. After rebooting, I started alsamixergui and delighted in
my newfound ability to turn on and off the various lights on top of
the device. With that out of the way, I decided to try to use it to
play some audio. I started rhythmbox and began to play an mp3. I got
about 30 seconds of noisy stuttering audio (still recognizably the
mp3) before rhythmbox froze. Just after that, my terminal froze. I
launched the system monitor to kill those processes, but then my
system monitor froze. Being a beginner, I thought restarting again
might help. My system completely froze in the shutdown process. I did
see a string of things related to alsa, such as:

alsactl: set_control:930: warning: name mismatch (speaker playblack
volume/master playback volume) for control #6.

alsactl: set_control: 932: warning: index mismatch (2/0) for control #6

alsactl: set_control: 932: warning (something... didn't write fast
enough) control #7

alsactl: set_control: 930: warning: name mismatch (headphone Playback
Source ...more I didn't catch

alsactl: set_control: 1025: bad control.8.value type...

and so on (there could be mistakes in the above... I didn't remember
well enough/write fast enough as they scrolled by). I had to pull the
power (ouch!) and then turn on the computer again.

After restart, I tried to open the same mp3 in audacity. It opened,
and I pressed play. Audacity produced less than five seconds of noise
(extreme distortion/almost white noise) before my whole system froze
completely, leaving me with no other choice but to pull the power
again (OUCH!).

Where may I have gone wrong? What can I fix? Loaded modules?
asound.conf? Maybe two soundcards (laptop's own and this usb one)?
Something else? I suspect that my inexperience has lead me to
inadvertently break something. Ideas?

This is on an IBM Thinkpad X31 with Ubuntu Hoary Hedgehog 5.0.4
(kernel 2.6.10). The Audigy is running through a USB hub to one of the
thinkpad's usb ports. I have used the card in Windows, so I know it
can work properly.
