The man pages will give you the best information. You can also see the list of options by # amixer --help I attached a few quick examples for your reference. amixer,without any parameters, gives you the full list of controls. On my dm355 board, I have the following output. # amixer Simple mixer control 'PCM',0 Capabilities: pvolume Playback channels: Front Left - Front Right Limits: Playback 0 - 127 Mono: Front Left: Playback 112 [88%] Front Right: Playback 112 [88%] Simple mixer control 'Line',0 Capabilities: volume Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: 0 - 9 Front Left: 1 [11%] Front Right: 1 [11%] ... If you want to look at specific control do (I use "Mic" as an example) # amixer sget "Mic" Simple mixer control 'Mic',0 Capabilities: volume Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: 0 - 9 Front Left: 9 [100%] Front Right: 9 [100%] To change the value do (again using "Mic" as an example) # amixer sset "Mic" 5 Simple mixer control 'Mic',0 Capabilities: volume Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: 0 - 9 Front Left: 5 [56%] Front Right: 5 [56%] Regards, Steve _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
