jaroslav: i've fixed the problem and made a patch.
i'm using the delta audiophile 2496. the following two lines do not work.
they end up muting both sides.
amixer cset iface=MIXER,name='Multi Capture Switch',index=[0-9] 0,1
amixer cset iface=MIXER,name='Multi Playback Switch',index=[0-9] 0,1
i can get values=off,off, values=on,on, values=off,on, and values=on,off
using envy24control, but i could not get values=off,on using amixer, as
there was no statement(?) to adjust ptr when the first value was 0 or
equivalent (see below). i've fixed this and attached a patch. i made
sure that it works with the latest cvs version of amixer (which has not
changed since at least 10/20/01 other than the address of the fsf).
woohoo! my first real contribution to linux audio...
