Jonathan/Takashi,
I am sorry I have not replied earlier. I had
difficulty with the patch in my OpenSuse 10.1. I now
have a hard-disk installed Knoppix 5.0.1 and I can now
apply and test the patch properly.
Except for the lower volume in the headphone jack,
everything works fine. I just use the line jack for
the headphone if I require a louder output. The
speaker sound is actually much louder than in Windows.
Thank you for all the help. I now have a simpler mixer
control. Please let me know if you require any other
test.
Regards,
Val
