No sound with auich and Intel 82801DB/DBL/DBM ICH4

[dflemstr]

My laptop with an Intel 82801DB/DBL/DBM sound card does not emit any sound. This happens in Haiku hrev33067.

The media_addon_server uses 100% CPU time on this system while the auich driver is loaded. The syslog gets filled with the following two lines (repeating):

KERN: auich: last read/write registers: 26/0
KERN: auich: codec semaphore timed out!

Removing the auich module and rebooting "fixes" the issue, meaning that CPU usage goes back to normal, but there is still no sound.

Possible duplicate - different audio controller but same symptom as in #4460.

Indeed, the pci configuration for the audio device is missing:

After the system has booted, at a certain point (perhaps starting the media server), when the cpu is about 0%, the system freezes. No kdl or something else. I can only use the power-button to reset the system, nothing else works. It is interesting that using VirtualBox, there Haiku can use the auich driver without problems. After I remove the link to the auich driver (the link is in a directory called hmulti i think) I can start haiku normally, but of course without sound. I tested it on hrev35274. I think on the first release of Alpha 1, I had sound.

I tried alpha1 again, to see if the auich driver works there. It doesn't work, but at least it doesn't freeze the system. The auich driver is listened in the media-preferences, and and volume controls can be manipualted.

Now something strange I have noticed. On the nightlies, the system always freeze before it reaches the desktop. And I can start haiku only with "same mode". If I start in safe mode, and then I go the media-preferences and restart the media server, it freezes the system again. (and nothing but the power button helps, no KDL).

BUT..... But if I start in "safe mode" and then I move the "auich" driver to the home-folder, and then move it back to the same location. Then I can start the media-server! It doesn't freeze the system anymore. The auich driver is listened in the media preferences, and the controls can be manipulated. But it still doesn't output sound. If I start cortex I see that media player is just connected to the mixer and nothing more. If I try to pull from the add-ons menu "Auich ICH" on main cortex-window, cortex gives the message in the status-bar: Could not instantiate 'Auich ICH' (Name not found)

I just noticed this bug in Alpha 2, but it is fixed as of the latest revision, ​r37240. It works for that card in QEMU at least, I don't know if it works on actual hardware.

Please try again with hrev39310 or newer. It should not help with the sound given the non configured device, but avoid troubles booting.

[cipri]

it didn't help. It's still the same.

[korli]

You mean it still freezes ?

[cipri]

yes, it still freezes. But if I install opensound, it doesn't freeze anymore, even if auich is not removed.

Please retest with a recent nightly.
