Asus Maximus V Gene with SupremeFX III working

[Bruners]

Just want to report that the Asus Maximus V Gene's onboard SupremeFX II works with OSS4,

However I'm getting some kernel messages during boot

Code: Select all

oss_hdaudio: HDA codec 0x10ec0899 not known yet
oss_hdaudio: HDA codec 0x10ec0899 not known yet


And during X startup/app launching which seems to be mumble

Code: Select all

osscore: launch_output while not prepared. Engine=12

Other than that it seems to be rock solid apart from having to few "vmix-engines"

Code: Select all

osscore: Failed to create a vmix engine, error=-16
osscore: Failed to create a vmix engine, error=-16
osscore: Failed to create a vmix engine, error=-16


If there is any info I can contribute with to get these messages fixed I would be happy to help

Does HW mixing work with your ALC899 codec?

It deserves a try.
It turned out that even "backwarded" Intel HDA codecs are capable of HW mixing (as well as "ultra backwarded" Intel AC'97 Audio Codecs), although, of course, it may not always work with buggy drivers, or "very advanced open-source crap" (ALSA).

I am now testing ALC887 codec (Intel HDA):

Code: Select all

$ ossmix
Selected mixer 0/High Definition Audio ALC887

$ lspci -vnn
00:1b.0 Audio device [0403]: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller [8086:1e20] (rev 04)
   Subsystem: Giga-byte Technology Device [1458:a002]
   Flags: bus master, fast devsel, latency 0, IRQ 22
   Memory at f7e10000 (64-bit, non-prefetchable) [size=16K]
   Capabilities: <access denied>
   Kernel driver in use: oss_hdaudio
   Kernel modules: snd-hda-intel

Although ALC887 is neither "supreme" nor "advanced", it does support HW mixing with OSS4.
HW mixing can be enabled/disabled in ossxmix with a mouse click.
You can record the so-called "total mixed output" (playback + mic)

HW mixing is easy to detect:
1. Plug a microphone into your PC.
2. Speak into the microphone (but do not run any recording software).
3. Try different settings in ossxmix.

If you hear your voice in the speakers, it means that HW mixing is enabled.
