Do you still load the module with "model=test" option? If you do, I 
don't quite understand the problems but well, nevermind. Try loading it 
with a "model=acer" option. You should get much less controls - just 
those that work (or should work) on an Acer notebook. Set the "Line 
jack" control to Line In, and the "Mic jack" control to Mic 50pc. Unmute 
and increase volume in all channels. Try playing some audio file then. 
If you hear it (the sound should now be redirected to the internal 
speakers or the headphone jack, if there's anything plugged in). If it 
works, try loading the module without any parameters and see if your 
notebook is autodetected, as it should be.

This Audio CD problem has been discussed on the list. I have a suspicion 
that maybe Acers are expecting your software to do Audio CD decoding (as 
opposed to the CD drive itself). If you load the module with 
"model=acer" parameter, you'll see the CD volume control in the mixer. 
Be aware that it does NOT affect CD playback volume (yet?), so don't get 
stressed about it. ;)

Yes. All volume switches only affect how a certain channel is 
preamplified before going to the mixer, not after leaving it. Master 
(output) volume can only be controlled by LOUT1 and LOUT2 (where 
applicable) controls. In "acer" model, LOUT1 is called "Master".

Probably...

One last thing (just not to miss a silly thing): if you edited the 
patch_realtek.c previously, you should rename/delete, and then retrieve 
a fresh copy of it from the CVS, because simple "cvs update" won't 
retrieve it for you if you have edited it before.

best regards,
RQ
