No sound on ATI IXP with Realtek ALC655 rev0 (MSI Megabook S270)

No sound on ATI IXP with Realtek ALC655 rev0 (MSI Megabook S270)

Hi all,

despite enabling all mixel elements and increasing all sliders to the maximum 
(or to other reasonable values) there is no sound from the internal speakers 
on an AMD Turion based MSI Megabook with ATI chip and ALC655 rev0.

There is a very low output on the headphone jack, but it is really far too low 
and barely hearable when the Master and PCM slider are set to the maximum.

I tried both 2.6.12 and 2.6.13 as well as building 1.0.10rc1 seperatly.

Any idea? What kind of debug output would be helpful?

Sincerely yours,

You aren't using the Gnome or KDE mixer are you?

Make sure you try it with alsamixer, and especially check the "External
Amplifier" control (if you have it).

The console is with me, so I used alsamixer as always. I tried every control - 
including external amplifier. Though the later has no effect at all.

It's a known device which doesn't work so far.
Possibly missing a vendor specific configuration like GPIO...

Anything I could look into to find out?

At the last time Harald Welte and I tried to debug this, we couldn't
find the culprit.  See the thread on alsa-devel in June.

The ac97 registers seem OK, and I don't see any relevant registers of
ATI IXP chip...

Could you try to give MSI a pressure to help this out a bit?
(You can pass them my address if necessary, of course :)

Anyway, /proc/asound/card0/codec97#0/* files would be needed for
further debugging.

If it's related with EAPD, does changing the ac97 reg 7ah (misc
control) bit 1 have any influence?
You can change the ac97 register value by writing above ac97#0-0+regs
file.  See alsa-kernel/Documentation/Procfiles.txt for details.

Yes. The register had 0:7a = 2092, I echoed "7a 2090" into the proc file and 
voila - sound is working!

Thank you very much!,

That's good to know.  Now we need to turn this on automatically at the
start up.

Could you attach /proc/asound/card0/codec97#0/* files?
Also please give the output of "lspci -nv", too.


thanks,

Takashi

Thanks, could you try the patch below?

I hoped there is something else to detect the spdif-input capability,
but it seems not.  So, blacklisting the pci ssid seems to be the only
way to go...

Harald, the patch might fix the problem on your laptop, too.
Could you check it?

Hi,

> Thanks, could you try the patch below?

Works for me (tm) for a make ; make install ; rmmod ; modprobe cycle. No 
reboot yet. But I'm confident that it will work and notify you if not.

Many thanks!

I found that Harald's case is a bit different.  It uses ALC658 instead
of ALC655, IIRC.
The patch below is a newer version with more comments.

Harald, please add the PCI SSID of your device in
alc655_is_using_eapd() function and let me know whether it works.

This patch must work with René's machine, too.

The PCI ID's are the same:

And unfortunately this patch also doesn't make the speakers work for me,

Hmm, did you turn on "External Amplifer" mixer switch?
Anyway, could you attach the contents of
/proc/asound/card0/codec97#0/* files again after the patch?

I tried it with enabled and disabled EA mixer switch, no change :(

However, I didn't reboot, I just unloaded snd_atiixp and snd-pcm-ac97
(unpatched), loaded snd-pcm-ac97 (patched) and snd_atiixp on top of it.
Will try a "clean boot" just now.

Hmm, the bit 1 isn't set, i.e. the patch didn't do the right job.

Could you try to tune this manually by writing like
	# echo 7a 40b2 > /proc/asound/card0/codec97#0/ac97#0-0+regs
as root?

Rebooting didn't change anything either.  But I thought I'd try it just
to make sure

done.  doesn't change anything.  I again re-tried with EA on/off and
headphones plugged in and not plugged in.  It still behaves exactly like
the original kernel.

It's a pity.  Just to be sure, compare the value of 0x7a in
/proc/asound/card0/codec97#0/ac97#0-0+regs file after the procedure
above.

I have no other clue yet...

yes, I did that.  the register has been set to the value I wrote to it.

No problem, it's not all that important... I didn't buy the device
because of it's lousy notebook speakers anyway ;)

Yesterday there was a bugreport, possibly about the same device as you
have.

Could you try the patch below?
The point of the patch is to turn on reg 0x74 0x0800.

There was a typo.  The fixed patch is below.

Thanks, I'll try later this afternoon.  

btw: In case this doesn't work, please don't invest any further time
into this.   The device was actually a GPL violation, and as I now see,
the vendor-provided kernel objectcode (based on 2.6.6) produces correct
sound output, whereas the sourcecode they ship doesn't.  So I've now
asked my lawyer to send them a nice letter indicating that the soucre
code they provide is not the "full corresponding source code" and that
they need to publish the changes they did - including those that make
the speakers work :)

I've checked it (on 2.6.13-rc6): It doesn't change anything for me (i.e.
headphone output works, speakers are silent).  What a pity.

You'll likely to modify the patch.  Check the second one I sent, and
add the entry of your PCI SSID.
