Hello list, My desktop has a 4.1 speaker system, connect to an Asus motherboard with a built-in ALC887 sound card. $ dmesg | grep ALC hdacc0: <Realtek ALC887 HDA CODEC> at cad 0 on hdac0 hdaa0: <Realtek ALC887 Audio Function Group> at nid 1 on hdacc0 pcm0: <Realtek ALC887 (Rear Analog 3.1/2.0)> at nid 20,26 and 24 on hdaa0 pcm1: <Realtek ALC887 (Front Analog)> at nid 27 and 25 on hdaa0 pcm2: <Realtek ALC887 (Onboard Digital)> at nid 17 on hdaa0 I am able to listen to the front but not to the rear speakers. I would like to adjust my audio system to 4.0/4.1, i.e., same audio in the rear and in the front speaker. Don`t care too much about real surround sound. All relevant sound modules are there, so I think problem is related to the configuration of the sound chipset. Searching in the Internet I figured out I could redefine a line-in jack (blue, where my rear speakers are connected) to line-out. So I did it: $ cat /boot/device.hints hint.hdac.0.cad0.nid20.config="as=1 seq=0" #hint.hdac.0.cad0.nid24.config="as=1 seq=1 device=Line-out" #hint.hdac.0.cad0.nid26.config="as=1 seq=2 device=Line-out" hint.hdac.0.cad0.nid26.config="as=1 seq=1 device=Line-out" $ cat /dev/sndstat Installed devices: pcm0: <Realtek ALC887 (Rear Analog 3.1/2.0)> (play/rec) default pcm1: <Realtek ALC887 (Front Analog)> (play/rec) pcm2: <Realtek ALC887 (Onboard Digital)> (play) pcm3: <USB audio> (rec) After boot in verbose mode I got: hdaa0: Pin sense: nid=20 sense=0x80000000 (connected) hdaa0: Pin sense: nid=26 sense=0x80000000 (connected) hdaa0: FG config/quirks: forcestereo ivref50 ivref80 ivref100 ivref pcm0: <Realtek ALC887 (Rear Analog 3.1/2.0)> at nid 20,26 and 24 on hdaa0 pcm0: Playback: pcm0: Stream cap: 0x00000001 PCM pcm0: PCM cap: 0x000e0560 16 20 24 bits, 44 48 96 192 KHz pcm0: DAC: 2 3 pcm0: pcm0: nid=20 [pin: Line-out (Green Jack)] pcm0: + <- nid=12 [audio mixer] [src: pcm, mix] pcm0: + <- nid=2 [audio output] [src: pcm] pcm0: + <- nid=11 [audio mixer] [src: mix] pcm0: pcm0: nid=26 [pin: Line-out (Blue Jack)] pcm0: + <- nid=13 [audio mixer] [src: pcm, mix] pcm0: + <- nid=3 [audio output] [src: pcm] pcm0: + <- nid=11 [audio mixer] [src: mix] pcm0: This means that both jacks in the motherboard are set to line-out and shoud work, right? Is there anything else I should set, maybe mixer in order to have a 4.0/4.1 audio system? Any ideas? Thanks, Luciano.
