Hey, I have an ESI MAYA44 USB+ (https://www.esi-audio.com/products/maya44usb+/) with 8 channels (2 stereo input + 2 stereo output) and a headphone jack:
uaudio0 at uhub0 port 3 configuration 1 interface 0 "ESI Audiotechnik GmbH MAYA44 USB+" rev 1.00/3.01 addr 2 uaudio0: audio rev 1.00, 8 mixer controls audio0 at uaudio0 uhidev0 at uhub0 port 3 configuration 1 interface 3 "ESI Audiotechnik GmbH MAYA44 USB+" rev 1.00/3.01 addr 2 uhidev0: iclass 3/0 uhid0 at uhidev0: input=8, output=8, feature=0 I would like to unmute the two stereo input channels to have them play at the same time via one of the output channels. However, I'm struggling a little. It seems that mixerctl has given both line channels the same identifier, so I can only unmute one of them. Also, only one output is listed although this card has two: inputs.line.mute=on inputs.line=191,191 inputs.line.mute=on inputs.line=191,191 outputs.spkr.mute=off outputs.spkr=255,255 record.line.mute=off record.line=0,0 record.enable=sysctl audioctl output: name=uaudio0 mode= pause=0 active=0 nblks=2 blksz=960 rate=48000 encoding=s16le play.channels=2 play.bytes=0 play.errors=0 record.channels=2 record.bytes=0 record.errors=0 Any idea what I'm missing?
