Hello,

 

Trying to get my onboard sound working on a Maximus Hero IX board with i5 7600k kaby lake.

Without any tinkering, the device appears in the sound card selection, but when chosen, it fails. After changing syslinux to the above, there were no changes (Sound device doesn't appear under "other PCI").

I've tried with and without ACS, no difference. Any ideas?

 

Thanks!!

Can anyone offer any help/advise on this? Using HDMI isn't really an option (I've got the Z906 speakers which require either 3.5 or spdif). Thanks!

Worst case scenario is you can get an audio extractor for the hdmi. ~$10

Hey Squid,

 

Thanks for the reply. I was looking at those, but it seems they only extract 2 channels. First world problems, I know, but I'd like to use my 5.1.

I think that using spdif it will do 5.1
