I get a decent looking set of alsa things in /proc/asound $ cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xfc300000 irq 22 and dmesg says that model=acer was selected reasonably enough. I can play audio down the logical sound devices, including cat /dev/urandom > /dev/dsp and the interrupt count goes up in /proc/interrupts. Alsamixer shows a bunch of things and I twiddled them all to no avail. There has never been even a click from the speakers or headphone jack on this machine. At least three funnies on this machine: 1) It is confused if it has ALC889 or ALC883 in there $ grep ALC /proc/asound/* -R /proc/asound/card0/codec#0:Codec: Realtek ALC889 <==== 889 /proc/asound/card0/pcm2c/sub0/info:id: ALC883 Analog <=== 883... /proc/asound/card0/pcm2c/sub0/info:name: ALC883 Analog /proc/asound/card0/pcm2c/info:id: ALC883 Analog /proc/asound/card0/pcm2c/info:name: ALC883 Analog /proc/asound/card0/pcm0c/sub0/info:id: ALC883 Analog /proc/asound/card0/pcm0c/sub0/info:name: ALC883 Analog /proc/asound/card0/pcm0c/info:id: ALC883 Analog /proc/asound/card0/pcm0c/info:name: ALC883 Analog /proc/asound/card0/pcm0p/sub0/info:id: ALC883 Analog /proc/asound/card0/pcm0p/sub0/info:name: ALC883 Analog /proc/asound/card0/pcm0p/info:id: ALC883 Analog /proc/asound/card0/pcm0p/info:name: ALC883 Analog /proc/asound/Intel/codec#0:Codec: Realtek ALC889 <=== 889 /proc/asound/Intel/pcm2c/sub0/info:id: ALC883 Analog /proc/asound/Intel/pcm2c/sub0/info:name: ALC883 Analog /proc/asound/Intel/pcm2c/info:id: ALC883 Analog /proc/asound/Intel/pcm2c/info:name: ALC883 Analog /proc/asound/Intel/pcm0c/sub0/info:id: ALC883 Analog /proc/asound/Intel/pcm0c/sub0/info:name: ALC883 Analog /proc/asound/Intel/pcm0c/info:id: ALC883 Analog /proc/asound/Intel/pcm0c/info:name: ALC883 Analog /proc/asound/Intel/pcm0p/sub0/info:id: ALC883 Analog /proc/asound/Intel/pcm0p/sub0/info:name: ALC883 Analog /proc/asound/Intel/pcm0p/info:id: ALC883 Analog /proc/asound/Intel/pcm0p/info:name: ALC883 Analog /proc/asound/oss/sndstat:0: ALC883 Analog (DUPLEX) /proc/asound/oss/sndstat:0: Realtek ALC889 /proc/asound/pcm:00-02: ALC883 Analog : ALC883 Analog : capture 1 /proc/asound/pcm:00-00: ALC883 Analog : ALC883 Analog : playback 1 : capture 1 2) from dmesg ALSA sound/pci/hda/hda_intel.c:1810: chipset global capabilities = 0x4401 ALSA sound/pci/hda/hda_intel.c:749: codec_mask = 0x3 ALSA sound/pci/hda/hda_codec.c:2211: hda_codec: model 'acer' is selected ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Headphone Playback Volume, skipped ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Speaker Playback Volume, skipped ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Mono Playback Volume, skipped ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Line-Out Playback Volume, skipped ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Speaker Playback Switch, skipped ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave Mono Playback Switch, skipped ALSA sound/pci/hda/hda_codec.c:1073: Cannot find slave IEC958 Playback Switch, skipped 3) there is a funny embedded capacitive volume control thing on this device, whether it gates output by itself or is just a bunch of special keyboard keys, I dunno. Any ideas, more information needed? -Andy
