Subject: dmix bugs. sounds very broken up.
Date: Mon, 01 Sep 2003 01:59:18 +0100 [thread overview]
Message-ID: <3F5299E6.7040408@superbug.demon.co.uk> (raw)
I have found two problems with using the dmix alsa device name.
1) snd_pcm_hw_params_can_pause (params) causes alsa-lib to assert!
2) Sound is broken up.
a) It can only function with 2 periods, why is that? Having 8 periods
might be better, although "front" works fine with 2 periods, but "dmix"
with 2 periods fails.
b) Of the 2 periods, it sounds like sound is only being played from one
of the periods, with silence for the other period.
Summary: -
If I use device name "front", there are no problems with sound output.
If I use device name "dmix", there are the above problems.
Cheers
James
