Thank you. Where those hw numbers come from? I tried the following under Gnome: # speaker-test -t wav -c 2 -D hw:0,0 speaker-test 1.0.25 Playback device is hw:0,0 Stream parameters are 48000Hz, S16_LE, 2 channels WAV file(s) Playback open error: -16,Device or resource busy # /etc/init.d/pulseaudio stop [warn] PulseAudio configured for per-user sessions ... (warning). # speaker-test -t wav -c 2 -D hw:0,0 speaker-test 1.0.25 Playback device is hw:0,0 Stream parameters are 48000Hz, S16_LE, 2 channels WAV file(s) Playback open error: -16,Device or resource busy # speaker-test -t wav -c 2 -D hw:1,0 speaker-test 1.0.25 Playback device is hw:1,0 Stream parameters are 48000Hz, S16_LE, 2 channels WAV file(s) Playback open error: -2,No such file or directory # speaker-test -t wav -c 2 -D hw:2,0 speaker-test 1.0.25 Playback device is hw:2,0 Stream parameters are 48000Hz, S16_LE, 2 channels WAV file(s) Playback open error: -2,No such file or directory Just wondering what change does in second number: # speaker-test -t wav -c 2 -D hw:0,1 speaker-test 1.0.25 Playback device is hw:0,1 Stream parameters are 48000Hz, S16_LE, 2 channels WAV file(s) 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 = 2,730392 0 - Front Left 1 - Front Right Time per period = 2,986731 0 - Front Left 1 - Front Right Still no sound. So no success. # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: ALC887-VD Analog [ALC887-VD Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: ALC887-VD Digital [ALC887-VD Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 I think this means that alsa detect my audio device.
