Hi,
thx for responses. I did a few more experiments:
-under win2K
1) started regular CD player, can control the volume by CD
slider, unplugging the analog cable stops the music
2) started iTunes, can control volume by Wave slider, unplugging
the analog cable does not affect the playback
in both cases, master volume also works
-under Linux
3) started various players, unplugging the analog cable does not
affect the playback, only master volume works, PCM (wave) slider does
not work
master volume also works
Conclusion:
- it is possible to have digital signal thru the IDE (I was not
aware before)
Question:
-why PCM input slider in the mixed does not control volume, does it
have the same function what MS Windows Wave

thx in advance,
