Subject: problems with mono audio.
Date: Thu, 11 Mar 2004 19:10:05 +0000 [thread overview]
Message-ID: <4050B98D.3030104@superbug.demon.co.uk> (raw)
Which devices can a mono stream be played on?
It seems that the only device a mono stream can be played on is the
"default" pcm device.
Devices like "front" and "rear" are stereo only devices.
It would be nice if alsa-lib would open one of these devices, and if the
application tries to set 1 channel instead of 2, then somehow make
alsa-lib do the duplication of the channels.
A similar thing should happen for "surround40" device. If 1 channel is
asked for, alsa-lib should duplicate it for all channels. If 2 channels
are asked for, then alsa-lib should create 4 channels automatically.
alsa-lib seems to manage to do this sort of thing for sample rates, and
sample formats, why not number of channels ?
Cheers
James
