Hi I have SL 5.2 on a Vaio VGN-FZ350 series and there is no sound out of the headphones. this is the output of amixer: $ amixer Simple mixer control 'Master',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 127 Mono: Front Left: Playback 127 [100%] [0.00dB] [on] Front Right: Playback 127 [100%] [0.00dB] [on] Simple mixer control 'PCM',0 Capabilities: pvolume Playback channels: Front Left - Front Right Limits: Playback 0 - 255 Mono: Front Left: Playback 214 [84%] [-8.20dB] Front Right: Playback 214 [84%] [-8.20dB] Does this mean the system did not recognize the headphones?
