Hello all,
about the problem with the ES137x driver I had (fxtv getting louder
everytime I switch the channel) I mailed Cameron Grant, maintainer of the
driver, about my problem and received the following answer from him. Due
to problems with his mail account he doesn't post it himself to the list
at the moment but allowed me to forward this mail.
Randall, if I understand it in the right way, Cameron thinks, the
behaviour of fxtv should be slightly different regarding the volume
setting.
Thanx, Oliver

this will occur with all cards, as the generic mixer code returns the actual
value set instead of the value it was told to set. according to the oss
specification, this is the expected behaviour. i am aware of the issue, and
if it continues to affect a significant number of applications, i will
adjust the mixer code.
