But the BIOS itself beeps through the sound-card at boot :/

Nope, unfortunately it doesn't. Still no Beep controls, no beep through
sound-card.

May I somehow provide any further data?
Or am I somehow able to tweak it? Is there a module parameter to set
this SSID bit? I mean, it did work before... :)


Thanks for you help & regards

Why did the tachyon cross the road?
Because it was on the other side.

Even grub's beep (play 480 440 1) goes through the sound-card. So it
seems like the BIOS leaves everything set up working as well.

Please don't get me wrong. I'm not saying the driver does something
wrong, I'm sure it doesn't. I'm just sure that if I could convince it to
behave as if it would have detected the Beep pin everything would work
fine again because it did before...

Attached.

This is from a kernel with both patches applied you sent me.

Nope, no sound. But I guess this wasn't the intention of the patch. Now,
no beep input is registered anymore - which was the intention, I guess.

> But it doesn't go through codec, thus no volume control.

If you mean it should go through the 5V PC Speaker (i.e. pcspkr) - I
don't have such a thing connected. I always appreciated having volume-
and mute control over the beep at night when you can't get away from
work but don't like to wake up anybody just because command completion
beeps, because you pasted something in the wrong window, or whatever.

Mh, 1 probably :)

$ cat /etc/modprobe.d/local-alsa.conf
options snd-hda-intel model=asus-p5q
install snd-hda-intel /sbin/modprobe --ignore-install snd-hda-intel $CMDLINE_OPTS && { cd /sys/class/sound/hwC0D0; echo -n 1 > subsystem_id; echo -n 1 > reconfig; : ; }

Yep, Beep is back :)

Btw...

Well, the Board is from 2007, the last BIOS is from Aug 2009. I don't
think Asus will provide an update just for that :)


Thanks for your help

Unfortunately, the chip vendors have delayed the availability of the
long-promised crystal-ball peripherals yet again, forcing the governor
code to rely on heuristics; once again, software must make up for
deficiencies in the hardware. -- Jonathan Corbet, LWN

Yes, it does and it works. Thank you very much again.

I just checked 2 more boards - the P5E-VM HDMI (P5E-V HDMI's little
brother) is already covered by the quirk and P5Q-EM (G45) seems to
specify it correctly (subsystem_id = 0x104382fe - seems I got the logic
wrong before - LSB isn't set here and it works).
