I have a recurring problem with ALSA-lib that _seems_ linked to the 1.0 release candidates. With one certain application (I've written a dynamically loaded PortAudio plugin for a mediaplayer), ALSA-lib will report maximum zero capture and playback channels for both my devices (nVidia nForce2 and RME DIGI9636). When running minimal PortAudio programs capabilities are reported correctly. I've managed to fix this in the past by reinstalling 0.9.8, but 1.0rc2 has worked for a while without problems. Today the same thing happened though, consistently zero available channels would be reported, with this one app (using a PortAudio output plugin). So I reinstalled 0.9.8, and rebooted. The problem was still there the first time I ran the app after reboot (with 0.9.8 installed) though, the second time it was gone. Weird, huh?
I'm using the ALSA-driver version compiled into the 2.6.1-rc1-mm1 kernel, which version is this, 1.0rc*? Could there be a version incompatibility between driver and lib? I don't think there's anything special to the way I open and query the card, I simply do a snd_pcm_open followed by a snd_pcm_nonblock (the open mode could be nonblocking), followed by snd_pcm_hw_params_any and then snd_pcm_hw_params_get_channels_max. Has anyone experienced similar behaviour?
Thanks in advance
