You mentioned the mic on your usb is working, then it is a setting in your mixer that tells alsa to grab from the usb mic. amixer .... .... .... Simple mixer control 'Input Source',0 Capabilities: cenum Items: 'Mic' 'Front Mic' 'Line' Item0: 'Mic' .... .... .... or amixer .... .... .... Simple mixer control 'Input Source',0 Capabilities: cenum Items: 'Mic' 'Front Mic' 'Line' Item0: 'Front Mic' .... .... .... thus for me the first one enables the USB mic and the second one the built in mic in the notebook. (Line is self explaining) Check out your mixer settings (amixer, alsamixer or kmix/gnome-mixer) and switch to the other mic - try the first command and the indicator #+ | 00% should change when recording some sounds. i.e. ###### + | 87% the nice thing with this test is that you don't need boxes or x to setup the sound system - I love linux and debian in particular. regards -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

Ha! Discovered that in alsamixer eventually. Couldn't make sense of amixer output - is it reading the same config as alsamixer? It's got to be, right? Alsamixer has a column for line, cd and mic which allowed me to take mute off from mic and now it comes thro from this mic on the soundcard to the speakers, but I still can't get anything with aplay or with audacity. Audacity has recording device choices of ALSA HDA Intel ALC882 Analog hw:0,0, hw:0,1 and hw:0,2 Don't know what to make of it. This is a amixer output: [....] Simple mixer control 'Front Mic',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 24 [77%] [1.50dB] [on] Front Right: Playback 24 [77%] [1.50dB] [on] Simple mixer control 'Front Mic Boost',0 Capabilities: volume Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: 0 - 3 Front Left: 2 [67%] Front Right: 2 [67%] [....] Simple mixer control 'Input Source',0 Capabilities: cenum Items: 'Mic' 'Front Mic' 'Line' 'CD' Item0: 'CD' Simple mixer control 'Input Source',1 Capabilities: cenum Items: 'Mic' 'Front Mic' 'Line' 'CD' Item0: 'CD' Simple mixer control 'Input Source',2 Capabilities: cenum Items: 'Mic' 'Front Mic' 'Line' 'CD' Item0: 'Front Mic' -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

I can't figure out why you recommend changing 'input source 1'. What about 0 and 2? And anyway, I can't figure out how to change them in alsamixer (there seem to be no options for anything except mute), nor in amixer with its sset and cset parameters. And if that doesn't sound like I'm having a bad time, Java has just decided it is getting upset with what I'm doing and can't use sound anymore: Error: Sound line is not available.javax.sound.sampled.LineUnavailableException: line with format PCM_UNSIGNED 11025.0 Hz, 8 bit, mono, 1 bytes/frame, not supported. It was happy enough until I started messing with the mic - I wondered why my Java app had gone silent. Not that it was that noisy. Sorry if this is getting boring but if there's a good source for documentation on this stuff, just point me at it and I'll figure it out. rgds Adam -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
