> What about `amixer set PCM unmute 80%'? -bash-3.1# amixer set PCM unmute 80% Simple mixer control 'PCM',0 Capabilities: pvolume Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 25 [81%] Front Right: Playback 25 [81%] Very odd. Same thing, the '[on]' or '[off]' indicators do not show up on running 'amixer set PCM unmute 80%'. The sound chip on the board is AT73C213 (www.atmel.com/dyn/resources/prod_documents/doc2708.pdf). The probability of it being a device driver issue is less, since the same device driver was demonstrated to work on another AT91SAM9261-EK board. Trying to cover all bases on the software front. thanks.
