Install of ArcaOS 5.03 failed after first boot.

Install of ArcaOS 5.02 was OK, it runs perfect but AUDIO fails.

At Internet says "Blond Guy" to add parameter /A:1 to UNIAUD32.SYS but it had no effect.

Send now ticket first without attachment due error befor. Then I try it with attachment again.

Thanks for Your efforts.

There was an experimental update to the driver updated yesterday (May 6, 2020) posted on the OS2World Forum. I guess it would not harm to give it a try to provide feedback.,2436.0.html

The T540 has been supported in Arca Noae Uniaud builds for some time (surely, ArcaOS 5.0.4 ships with a Uniaud build which supports the T540 and T540p).

While the latest test build from Paul will surely work, so will the latest Uniaud from Arca Noae, and tickets for any issues with that build should be opened there.
