I have a model 0768 A53 with a fresh install (plus updates) of Edgy. I unsuccessfully tried rebooting after setting /etc/modprobe.d/options to options snd-hda-intel model=laptop-eapd and options snd-hda-intel I unsuccessfully tried all the paths at https://help.ubuntu.com/community/SoundTroubleshooting. Finally, I removed then installed my sound from a fresh kernel. sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils sudo apt-get install linux-sound-base alsa-base alsa-utils I also reset /etc/modprob.d/options, so everything should be at the clean state. My modem is enabled in BIOS. Here are my current stats: $ tail -2 /proc/asound/oss/sndstat mixers: 0: realtek id 862 $ amixer -c0 simple mixer control 'master',0 capabilities: pvolume playback channels: front left - front right limits: playback 0 - 64 mono: front left: playback 64 [100%] front right: playback 64 [100%] simple mixer control 'pcm',0 capabilities: pvolume playback channels: front left - front right limits: playback 0 - 255 mono: front left: playback 255 [100%] front right: playback 255 [100%] simple mixer control 'capture',0 capabilities: cvolume cswitch capture channels: front left - front right limits: capture 0 - 31 front left: capture 22 [71%] [on] front right: capture 22 [71%] [on] $ aplay -l **** list of playback hardware devices **** card 0: intel [hda intel], device 0: hda generic [hda generic] subdevices: 1/1 subdevice #0: subdevice #0 $ lsmod | grep snd* snd_hda_intel 20116 1 snd_hda_codec 164608 1 snd_hda_intel snd_pcm_oss 47360 0 snd_mixer_oss 19584 1 snd_pcm_oss snd_pcm 84612 3 snd_hda_intel,snd_hda_codec,snd_pcm_oss snd_timer 25348 1 snd_pcm snd 58372 8 snd_hda_intel,snd_hda_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer soundcore 11232 1 snd snd_page_alloc 11400 2 snd_hda_intel,snd_pcm $ modinfo snd-hda-intel filename: /lib/modules/2.6.17-11-generic/kernel/sound/pci/hda/snd-hda-intel.ko license: gpl description: intel hda driver vermagic: 2.6.17-11-generic smp mod_unload 586 regparm gcc-4.1 depends: snd-pcm,snd-page-alloc,snd-hda-codec,snd alias: pci:v00008086d00002668sv*sd*bc*sc*i* alias: pci:v00008086d000027d8sv*sd*bc*sc*i* alias: pci:v00008086d0000269asv*sd*bc*sc*i* alias: pci:v00008086d0000284bsv*sd*bc*sc*i* alias: pci:v00001002d0000437bsv*sd*bc*sc*i* alias: pci:v00001002d00004383sv*sd*bc*sc*i* alias: pci:v00001002d0000793bsv*sd*bc*sc*i* alias: pci:v00001106d00003288sv*sd*bc*sc*i* alias: pci:v00001039d00007502sv*sd*bc*sc*i* alias: pci:v000010b9d00005461sv*sd*bc*sc*i* alias: pci:v000010ded0000026csv*sd*bc*sc*i* alias: pci:v000010ded00000371sv*sd*bc*sc*i* srcversion: 31ca0c84834dee3882349d3 parm: enable:bool parm: single_cmd:use single command to communicate with codecs (for debugging only).
