Unfortunately, I don't hear anything when testing this device: root@intel-corei7-64:/etc# speaker-test -t sine -f 1000 -D "hw:0,3" -c2 speaker-test 1.0.27.2 Playback device is hw:0,3 Stream parameters are 48000Hz, S16_LE, 2 channels Sine wave rate is 1000.0000Hz Rate set to 48000Hz (requested 48000Hz) Buffer size range from 64 to 16384 Period size range from 32 to 8192 Using max buffer size 16384 Periods = 4 was set period_size = 4096 was set buffer_size = 16384 0 - Front Left 1 - Front Right Time per period = 5.638792 0 - Front Left 1 - Front Right Time per period = 5.973074 0 - Front Left 1 - Front Right At this point, this is very possibly a Linux issue. Marking as resolved and opening an OS bug for no playback. 44425 2 dvhart 2014-07-10 17:19:37 +0000 ALSA support is restored in Firmware 07-10, aplay and speaker-test function as expected.
