ALSA: hda - proc - show which I/O NID is associated to PCM device
Output something like: Node 0x02 [Audio Output] wcaps 0x11: Stereo Device: name="ALC888 Analog", type="Audio", device=0, substream=0 Converter: stream=0, channel=0 ... Signed-off-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>
