I'm using plughw:1,0 device to capture and plug:'dmix:SLAVE="hw:1,0"', everything works fine (i mean play and capture), but when i try to close capture handle - snd_pcm_close(dev_handle) i get following output: ALSA lib pcm_hw.c:370:(snd_pcm_hw_hw_free) SNDRV_PCM_IOCTL_HW_FREE failed: File descriptor in bad state ALSA lib pcm_plug.c:69:(snd_pcm_plug_close) plug slaves mismatch (second error about slaves mismatch appears not in all situation). After some debugging i found out following - - this error occures only if i use playback (yes, playback, and error while trying to close capture handle). If i don't open playback device - it doesn't happens - after this handle remains open, and i cannot open it again - if i close snd_pcm_close again, it finally closes, but it doesn't seems a nice solution - it happens only when i use dmix plugin, when i use just plug plugin - everything is OK Has anyone comments to this, is it some misconfiguration or something else?
