Well, after a LOT of mostly ALSA-unrelated tinkering, I finally have my M-Audio Mobilepre USB set up.
For the unfamilar: http://www.m-audio.com/products/en_us/MobilePreUSB-main-1.html BUT, it's still not quite right. The first microphone is stereo. (Channel 1) is stereo, I can hear it in both ears when listening to the monitor headphones. Channel 2, however, is mono! I can only hear it in my right ear. amixer spits out the following: $ amixer -c 1 Simple mixer control 'PCM',0 Capabilities: pvolume cvolume pswitch pswitch-joined cswitch cswitch-joined Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: Playback 0 - 31 Capture 0 - 31 Front Left: Playback 29 [94%] [on] Capture 29 [94%] [on] Front Right: Playback 29 [94%] [on] Capture 29 [94%] [on] Simple mixer control 'PCM',1 Capabilities: volume volume-joined Playback channels: Mono Capture channels: Mono Limits: 0 - 1 Mono: 1 [100%] Simple mixer control 'Speaker',0 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 30 [97%] [on] Front Right: Playback 30 [97%] [on] Simple mixer control 'Speaker',1 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 29 [94%] [on] Front Right: Playback 29 [94%] [on] I think that PCM,1 is supposed to be the second microphone input channel, which makes sense because it's listed as Mono. So it's definitely a settings/driver problem rather than hardware like a loose connection or something. So my question is two fold: 1) Any idea what is going on here? Why is it mono? 2) More importantly, is there any way I can change it to be stereo like the other microphone? Any ideas, suggestions, whatever would be greatly appreciated. I'm not sure what else to do at this point. I really need some help. Thanks, Josh ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
