Hi,
I am unable to use plughw:0,0 as a device string while calling err = snd_pcm_open (&alsa_dev, hw_from_default, SND_PCM_STREAM_PLAYBACK, 0);
The same call works with hw_from_default == 'default', but fails when it is 'plughw:0,0'. The error is cannot open audio device "plughw:0,0" (Device or resource busy)
I am using the latest snapshot of alsa-lib, alsa-lib20070821. I tried debugging but I cannot trace through the macros. As near as I can tell there have been no changes to alsa.conf, and this worked just fine before the latest upgrade alsa package alsa-lib.1.0.14-3
Is this a deliberate change in alsa that is known about, and is there a way to still get the functionality?
Thanks.
Forgot to mention that this is on Fedora Rawhide with a 2.6.23 kernel. Want to see if it is normal in the latest versions of alsa before I pursue it through bugzilla with Fedora.
