Hi...
During the last weeks, I tried to get that card to work with ALSA 0.9.3c.
Here's what I found:
- The card is not properly recognized by the driver. I added the card to the
drivers hardware list (see attached patch) which seemed to help somewhat.
- Without the external_amp parameter, sound is sometimes OK, sometimes
distorted, sometimes not available at all.
- With external_amp set, the card basically works, but there are some quirks
The remaining quirks are:
- After a cold boot, the driver loads OK. After some 2-3 minutes uptime,
there's a very loud crackling noise, independent of sound output (like very
high spikes in the output). This goes away after about 20 seconds. After
that, sound is either "normal" (definition of normal follows...) or entirely
gone.
- Unloading the driver module works. However, reloading the module fails the
first time. Trying to load the driver a second time is always successful. See
the "reload-module.txt" attachment for output.
- Sometimes, sound is distorted at high PCM volume settings, sometimes it
isn't. I have not found any way to reproduce this, it just happens from time
to time. (Lasts as long as the machine isn't power-cycled). Setting the PCM
volume down to about 77% avoids this.
- After rebooting from Windows, sound dies with a "plop" afer some minutes.
Reloading the module gives another few minutes of sound. (repeat ad nauseam)
In conclusion, I think there's something wrong with the initialization. My
configuration is similar to the one given on the alsa-project website. Are
there any known bugs or workarounds?
