ALC892 Support (Intel HDA) - HDMI

ALC892 Support (Intel HDA) - HDMI

[Jeremy Bush]

Hello-

I'm trying to get my Realtek ALC892 chip to work according to it's specifications over HDMI. The manufacturers site say it should be able to do 7.1+2 channels, 24bit audio and 192Khz sample rate. However, it seems that the ALSA drivers (even the ones from the realtek website) limit the output to 2 channels, 16bit, 88.2KHz.

Here is my system information that you can see these results:

http://www.alsa-project.org/db/?f=5b55a63fea6580dfcbf1a85c7c734f977df798f1

I see the ALC892 as being supported in the ALSA changelog, but I don't see any model options in Documentation/HD-Audio-Models.txt. I'm currently using "options snd-hda-intel model=6stack-digout" (as I have 6-jack with a SPDIF out on the motherboard) but I'm not sure that is actually doing anything.

What's the *actual* support of this chipset? Is what I'm getting now the best I should expect over HDMI? I saw support in ALSA and bought the motherboard expecting it to be fully supported since the changelogs say support was added.

I also tried with an ALC887 chipset as well, and got basically the same results.

Any help getting this to work would be appreciated. Let me know if there's any other information required.

Thank you-
Jeremy

7.1 is provided by 4 jack at rear panel ( green, black, orange and grey)
2 is provided by headphone at front panel

As your codec info does not have "Side Playback Channel" and "Side Playback
Switch", it look like the model is used for 5stack motherboard which support
5.1

Do you hear any noise since Valerio reported noise appear when using the
model=auto in

OK, so that has nothing to do with HDMI then.

I'm not actually trying to get analog working or the front-panel output. Only surround sound over HDMI. I have tried model=auto and didn't notice anything different than specifying the model.

So this seems to say I should be getting 7.1 over the HDMI output. What do I need to change in my config to actually get it? I tried messing around with /sys/class/sound/hwC1D3/user_pin_configs but I'm not sure what to change.

Do your hdmi monitor support 7.1 ?

Yes, it's connected to an Onkyo TX-SR607 7.2-Channel receiver.
