Acer Aspire 7720 without sound

Hello,

I just bought a Acer Aspire 7720, but couldn't manage to take any sound of it.

# lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

I have kernel 2.6.23-ARCH installed and have already ran alsaconf. The right modules seems to be loaded

# lsmod | grep -i snd
snd_seq_oss            29312  0 
snd_seq_midi_event      6528  1 snd_seq_oss
snd_seq                46800  4 snd_seq_oss,snd_seq_midi_event
snd_seq_device          6924  2 snd_seq_oss,snd_seq
snd_hda_intel         286624  1 
snd_hwdep               7300  1 snd_hda_intel
snd_pcm_oss            36896  0 
snd_pcm                68996  2 snd_hda_intel,snd_pcm_oss
snd_timer              19332  2 snd_seq,snd_pcm
snd_page_alloc          8072  2 snd_hda_intel,snd_pcm
snd_mixer_oss          14464  1 snd_pcm_oss
snd                    44644  11 snd_seq_oss,snd_seq,snd_seq_device,snd_hda_intel,snd_hwdep,snd_pcm_oss,snd_pcm,snd_timer,snd_mixer_oss
soundcore               6496  1 snd

I have followed forum threads about problems with intel HDA cards, but nothing that I have found worked.

Thanks

Re: Acer Aspire 7720 without sound

Try using this alsa patch:

wget http://launchpadlibrarian.net/8355113/patch_realtek.c-2.6.22-hack

then follow this howto https://help.ubuntu.com/community/HdaIntelSoundHowto
apply the patch with like this after extracting the alsa packages:

# cp /where/you/saved/patch_realtek.c-2.6.22-hack /usr/src/alsa/alsa-driver-1.0.14/pci/hda/patch_realtek.c
# cp /where/you/saved/patch_realtek.c-2.6.22-hack /usr/src/alsa/alsa-driver-1.0.14/alsa-kernel/pci/hda/patch_realtek.c

then continue following the HdaIntelSound howto.

I've only tried this with the 1.0.14 packages, perhaps if you compile the newest version it might work without the patch.

It worked for me tho'.

Re: Acer Aspire 7720 without sound

thank you moses,

you are right, the latest version already supports my card, I just had to put this line in rc.conf

options snd-hda-intel model=toshiba

Re: Acer Aspire 7720 without sound

Just for the record: Adding "options snd-hda-intel model=toshiba" to /etc/rc.conf  did not work for me.
However adding the same line to /etc/modprobe.conf works just fine.
