UNIAUD Update: Thinkpad X250 - The Perfect ArcaOS Laptop

(1/3) > >>

Sigurd Fastenrath:
Thanks to Abwillis1 (Bugtracker 2637) Sound is now working on the Thinkpad X250 (and evtl. some more other models) including Volume Control!

AbWillis1 writes i.e.:

With unitest1, I see that the speaker playback volume is 0.
With unitest1:
unimix -id1 -val87 -cnt0
unimix -id1 -val87 -cnt1

These can be added to startup.cmd if they produce sound like they look like they should.

So, The Thinkpad X250 is one of the recommended ArcaOS Laptops now, as there is:

- ArcaOS can be installed from USB Stick (BIOS settings needed)
- there is still USB 2.0 support with this Laptop
- FullHD Resolution is working
- LAN is working
- about 2.9 GB of RAM is visible, RAM Disk is working
- Sound is working with this patched UNIAUD (attached)
- DOS and WINOS2 are working (without DOS window) with the VIOP Patch

-> so I can start my ArcaOS Channel using this Hardware then!

All the congrats and credits to abwillis1 and the ArcaOS Team for geiving help, advice and support via the Bugtracker!

@ Blondeguy: can you test it with the T450s as I do not have this hardware anymore?
I will test it with the Thinkpad 25 as well.

EDIT: I deleted the uni file as I do not know by now if it is allowed to chare it or if it is due to softwaresubscriptions regulations not allowed.

Mike Kölling:
I can confirm for my X250, that Sound is now working.
Wiki for the X250 updated today.
Greetings form Potsdam / Germany,

Sigurd Fastenrath:
Just to inform: I have been contacted by ArcaNoae and informed that it was more or less not a good idea from me that I uploaded the uniaud test file to the Forums. I already did delete it on my own after a few hours.

So I do not know when this patch will be published and if it will be "closed source" or not. I write this because some users already asked me wich X250 model would fit best (indeed I would guess it will work with any X250 ::) ) and want to inform, that the sound driver may bot ne public available. Please keep this in mind once you plan to buy an X250. For more Information you better contact ArcaNoae direct.

All the best.

Hi Sigurd.

But I think it will be  ok to share the link  for the people that have access to the AN bugtracker.
Here it goes: https://mantis.arcanoae.com/view.php?id=2637

I have access to the new uniaud driver.

This works on the T450s slightly better than the UniAud32.sys in ArcaOS 5.0.4. In the new driver, the volume control works, while in the release driver, sounds are always the same level.

The same is true for the T540. I've been without working volume control for Uniaud so long I've forgotten how to properly test it. It seems to work better with the new driver. Other than volume control, for both these machines, there is very little difference. Neither machine can use the built in speakers.
