I have been unsuccessful getting sound from a motherboard (ASUS M4A87TD) running Debian Squeeze with kernel 2.6.32-5-amd64 and packages alsa-base 1.0.23+dfsg-2 and alsa-utils 1.0.23-3. I am in the audio group. lspci shows: 00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev 40) Speakers are plugged into the analog output in the back. I tried both audio BIOS settings: HD and AC97. aplay -l shows: **** List of PLAYBACK Hardware Devices **** card 0: SB [HDA ATI SB], device 0: VT1818S Analog [VT1818S Analog] Subdevices: 2/2 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 card 0: SB [HDA ATI SB], device 1: VT1818S Digital [VT1818S 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 alsamixer is turned all the way up for: Card: HDA ATI SB Chip: VIA VT1818S Item: Master Front [dB gain: 12.00, 12.00] but aplay and speaker-test are silent. alsactl init gives: Unknown hardware: "HDA-Intel" "VIA VT1818S" "HDA:11060440,10438416,00100000" "0x1002" "0x4383" Hardware is initialized using a guess method I installed the backported kernel 2.6.39-bpo.2-amd64 because the file /usr/share/doc/linux-doc-2.6.39/Documentation/sound/alsa/HD-Audio-Models.txt.gz has: VIA VT17xx/VT18xx/VT20xx ======================== auto BIOS setup (default) added at the end. It made no difference. alsamixer, F2 /proc/asound/version says: Advanced Linux Sound Architecture Driver Version 1.0.24 I tried booting the live distribution grml64_2011.12 . It has kernel 3.1.0-grml-amd64 and packages alsa-base 1.0.23+dfsg-4 and alsa-utils 1.0.24.2-4. With this, alsactl init gives: Found hardware: "HDA-Intel" "VIA VT1818S" "HDA:11060440,10438416,00100000" "0x1002" "0x4383" Hardware is initialized using a generic method While grml is booting, it plays few tones to the speaker, proving the audio hardware is working, but after that, aplay, speaker-test are still silent. I uploaded the results of alsa-input.sh to: http://www.alsa-project.org/db/?f=7984f940cfbbbb481d72e00c5a35e54a5dd5a2c7 Any ideas? ------------------------------------------------------------------------------ RSA(R) Conference 2012 Mar 27 - Feb 2 Save $400 by Jan. 27 Register now! http://p.sf.net/sfu/rsa-sfdev2dev2 _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
