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, 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)... But this can be confirmed, someone else (Cc'ed by this email) has the same Laptop bought in France as well, using the same OS (Arch Linux 64bit), same Kernel (2.6.31.6) but his BIOS is Version F.23, He does not have this problem, he can hear sound coming out of The left, right and LFE, but in my case only the left works..
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.
Attached to this mail, my alsa-info.txt (mine-alsa-info.txt) and his alsa-info.txt (his-alsa-info.txt)
Thank you for helping me!!
Regards, Wael
