Mark,
I don't have any experiences with your hardware and didn't think my
reply would be of much use to you, but running the exact command you
post on my cs4236 system produces sound that is under control of
alsamixer, as does -Dhw:0, so that suggests to me that aplay is directly
affected by the settings in the mixer.
Frank,
Actually, your results are extremely helpful. Now I know this is a
bug which is a step forward. Thanks.
My hardware (HDSP 9652) is currently unsupported, but we are trying
to get it to work. I just needed verification that the command worked
the way you say. I suspected it did.
Now, some cards do not have a mixer so they should not behave this way,
as I assume would be the case if there were something wrong with the
driver for a card that does have a mixer. In either event I would not
expect to see controls in amixer or the gamix graphical interface. If
you see them and they have no effect that sounds like a malfunction.
Couldn't find any answer to your channel question. My system does not
seem to provide a relevant option to explore this further. I fooled
around with -c and -I options but could draw no useful conclusions.
May I ask what hardware you are using, and if you attempted to use (or
could you try out?) both mono and stereo wave files? I am curious
whether for you a mono wave file would be played on all channels, as my
driver is currently doing, or just channel 1, and whether a stereo file
is played as mono or in stereo.
Anyway, your response was exactly what I was hoping for. Thanks much
for verifying this.
Cheers,
Mark
