Title: HD Audio not working on MSI A68HM-E33 Motherboard
Post by: mfny on April 27, 2020, 11:40:14 pm
Hi all,

Having an issue on this board whereby 2 "HD Audio" devices do appear in Hardware Manager drop down menu, but with no details on the Device tab when ether is selected(Name,Description,Vendor,Version) and no Audio works. I get the following in the Testlog:

Command line mixer for UNIAUD32. Version 1.1
Detected UNIAUD version 2.02.05
Detected 2 audio adapter(s)
Error: invalid number of PCM instances for adapter 0
Card info for adapter 0:
  num: 0
  id: Generic
  driver: HDA-Intel
  name: HD-Audio Generic
  longname: HD-Audio Generic at 0xfeb64000 irq 27
  mixer: ATI ID aa01
  componenets: HDA:1002aa01,00aa0100,00100500

Do you have something like this in Config.Sys to select which adapter to use?

DEVICE=K:\MMOS2\UNIAUD32.SYS /A:1

Hi Matthew, welcome to the forum.

Can you please share more information about your hardware. You can generate and share here your pci.exe report and lsusb report, I have this article that explain how to do that (https://www.os2world.com/wiki/index.php/Extracting_Hardware_Information_from_ArcaOS_and_OS/2).

Are you using ArcaOS ?

Regards

Setting this manage to get audio working but it is very poor quality, apparently this is a know issue with the codec on this board :(

Hi Matthew

Let me know if you can post the pci.exe report. Maybe I can compare the HardwareID with some other reports and with some luck maybe someone else reported a good result.

Regard

Why poor quality ?
You just select the correct audio adapter  (this is always the case when you audio has more than one adapter and the firs one doesn't work :D

follow instruction from here:

Poor quality in this case meaning crackles/pops/stutters. As to why this happens, I dont know ? I see it mentioned as being an issue for various Realtek ALC codecs for quite some time.

I have one of those. I haven't bothered to report it to Arca Noae, because it does the same thing in windows (not quite as bad). My sister has an identical machine, with the proper Realtek windows driver, and it is okay. From what I have been able to find out, there is an open input, that is not controlled, and that picks up any noise that may be nearby. The Realtek driver must have some way to turn it off, but that doesn't do us any good.

I have no issues with it in Windows but then I hardly use it, I have a external USB audio interface (Behringer UMC202HD) I use most of the time as I do music production.

Thankfully this works great instead on AracOS w/  the Lars USB drivers: https://www.amazon.co.uk/Sabrent-External-Adapter-Windows-AU-MMSA/dp/B00IRVQ0F8/ cheap and cheerful :)

If you properly installed all of the USB audio package,you will be able to use OS/2 Multimedia Setup Object to select between different sound drivers as that normally is a bit unintuitive and tricky under OS/2. Your Behringer should also be supported as the USB audio package also contains support for the new USB audio 2.0 standard, including all the sample rates and bit resolutions that are in use today.
If you also install the USBWAV package, you will also be able to play Alaw,Mulaw,MS Adpcm files (and a few others) as they will be autoconverted to PCM format.

I use the UMC202HD on my main system, so getting that Sabrent thing was the best option for something cheap that works to use on the build i am running ArcaOS on.
