[alsa-devel] No sound for HP Pavilion DV4z

[aeleneski at comcast.net]

Thanks for your time and all these suggestions. Still no luck though. 


Seems like you might not be able to have two files ending in alsa-base in 
the /etc/modprobe.d/ folder. That was the reason for the orange speaker indicator. I had 
alsa-base and backup-alsa-base, for some reason it was grabbing the settings 
from the backup. 

Anyway, with probe only, orange sound indicator, when doing aplay -l I get 

**** List of PLAYBACK Hardware Devices **** 
card 1: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI] 
Subdevices: 1/1 
Subdevice #0: subdevice #0 

Attached are the requested logs. 
I tried using the hda-verb command you supplied, the only difference is 
that upon restarting after setting the command, I noticed the speakers crack, but still no sound. 
Not really sure what I should be looking for here.

This isn't too bad, but...

This seems more serious.

And this is better. 
So, obviously the problem looks like the communication with the 
secondary codec.

OK, first try to load the module with probe_only=1 option. 
Reboot once after setting this model to restore the original BIOS 
setup. Then run alsa-info.sh --no-upload, and attach the generated 
file. If you get errors, try to get /proc/asound/card0/codec#* files, 
at least. 

Then set model=hp-dv5, reboot and get alsa-info output, too. 

Also, make sure to use the very latest alsa-driver snapshot, 
ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz 
Check the changelogs in alsa-driver*/HEAD and alsa-driver*/alsa-kernel/HEAD 
files. 

The problem could be the invalid BIOS pin setup. 
In that case, you can try to change the pin control manually via 
hda-verb program, such as, 

hda-verb /dev/snd/hwC0D0 0x0d SET_PIN_WID 0x40 

See Documentation/sound/alsa/HD-Audio.txt in the recent kernel 
(found in alsa-driver snapshot, too).
