Takashi,
I tried the snapshot from
ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz
last night with and without options still no go, the options I've tried:
- options snd-hda-intel enable_msi=
- options snd-hda-intel enable_msi=1 single_cmd=0
power_save_controller=0 power_save=0 model=hp-dv5
power_save should be irrelevant. And model=hp-dv5 and enable_msi=1 are already turned on as default in the recent version.
The next would be model=auto to avoid hp-dv5 quirk.
Also, it's helpful if you give a summary of your problems again.

Takashi,
I just tried 'options snd-hda-intel enable_msi=1 model=auto' Didn't have much effect, the same problem (sound only from left speaker), always the same result with 'speaker-test -c6 -twav' I can only hear 'Front Left'
Summary: =======
I have an HP DV7-1299EF, BIOS (Version F.2C, F.2A and F.23) , Due to a BIOS BUG, the BIOS report only one speaker as an output so the driver does not know how to use pins in order to have a stereo output ( at least that's what you told me last month when you analysed the alsa-info output)... And so one speaker, the left speaker is the only speaker currently working under Linux.
First I suspected a hardware problem so 2 days ago I restored Windows, tried the sound it works, and I updated my BIOS (it was version F.2A before) but sadly it has the same BUG, I also tried reverting back to F.2A and further back to F.23 same result...
Attached to this mail, my alsa-info.txt
Thank you for helping me!!
Regards, Wael
