No sound with 82801H (ICH8 Family) HD Audio Controller, SXCE

[siva.ss.kumar]

Yes. I get the same "Unknown HDA codec 0x14f12c06" error during boot.
Hope the next version of OSS driver fixes it. Thanks

The sound from the headphones was actually working before I did anything with ossxmix; ossxmix just allowed me to see the levels. Sounds like you may be in the same boat as Mitdasein, with unrecognized codecs still.

Mitdasein, this appears to be the unrecognized codec you have:
Analog Devices AD1984
http://www.analog.com/en/prod/0,2877,AD1984,00.html

jBefore I get myself in over my head (it's been a fewyears since I did any C programming) what's the difficulty level to add support for an unrecognized codec?

I might have a couple of hours to look at the code today, I suppose I'll pull it down and see what it is.

I got the codec out of Alsa but it's different enough to requre more of a learning curve in OSS than I can afford right now. If anyone at OSS wants the appropriate patch in Alsa to work from let me know.

we've been working on fixing up the HDaudio codec stuff - there should be a new version this week (atleast a beta/rc version).


I would suggest that you give the new code a try and then if this still doesn't work, we should work together to get the issues fixed.

Thanks, I will definitely give the new code a try and if it doesn't correct the issue I will do anything I can do to help you guys support the codec.

Hi all,
I still get:
hdaudio: Unknown HDA codec 0x14f12c06

for the latest test version oss-v4.1test0-071114-src-gpl.

the device:
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)


I get a low sound output volume and no mixer.

I would ignore; "Unknown HDA codec 0x14f12c06" it is a total Red Herring as this refers to a Conexant HSF soft modem so it is extremely unlikely that this device will ever be supported by 4front-tech.

There will however be another audio codec attached to the HD Audio controller and this will be the multimedia audio device.

Hi,

I can report that the sound is working correctly for the hardware in the thread topic, except for the fact that the external speakers are not muted when headphones are plugged into the headphone jack. The external speakers must be muted via ossxmix AFAICT.

Many thanks to the OSS guys for providing an audio solution on this platform!!!

Hi,

I have the same problem in my HP Compaq 6720s:

When I boot the system I receive the same error message, but different codec:

"Unknow HDA codec 0x011c11040"

The device I have is 82801H (ICH8 Family) HD Audio Controller.

I have instaled the last version of opensound drivers but the problem is still appearing.
Let's see if a new version fix the problem...

Thanks and best regards

[seawright]

The unknown codec refers to your modem.
Except for this error message are there any other problems with the OSS sound driver & does the sound system function satifactorily?

Hi,

I can reproduce sounds using the /usr/bin/osstest
The test is ok, but the sound of the speakers is not disabled when I plug in the headphones, as reported by another users.

But this is the only test I can do, because when I start any sound application (realplayer, etc) system reports that another program is using the sound device, and if I try to configure the volume with the right-bottom icon, a message error is reported:

"Couldn't open mixer device /dev/audioctl"

Do you know how to solve it?
Thanks and regards

[seawright]

Can you play a .wav or .au file with ossplay or does that also give an error message.

run drvconfig and run ossdevlinks -r and now run realplayer.

Hi,

I executed drvconfig and ossdevlinks -r but the problem is still happening.

When i try to run an audio file with realplayer it appears an error message:

Error
Cannot open the audio device. Another application may be using it.

If I try to open ossplay, the error message is:

# ossplay
/dev/dsp: No such file or directory

The sound device file is missing from /dev.
You should try re-installing OSS.

I've reinstalled the oss package but it didn't solved the problem.
For your information, it doesn't exist any file or folder called /dev/dsp

Regards and thanks for your support

What output do you get from:
ls -l /dev/oss/hdaudio0/
