Hi Dave,

I'm afraid I cannot add much in terms of a "fix", but I will say this is interesting because having set up my dual display config here (Dell DU2412M) and being fed by my old trusty ATI X850XT PE, I am dealing with 1 of the units being hooked up through DVI and the 2nd one through VGA.

This is primarily a limitation of the current SNAP drivers, which do not support the ATI card's dual DVI ports to drive matching DVI ports on the display units.

The end result is that the VGA connected 2nd display is a little fuzzier (barely there, but my eyes pick this stuff up, so I can see it) and it does get slightly impacted by the VGA port's 'Pixel Clock' and 'Phase' settings. This sometimes results in that tell-tale noise when you display some dithered colour & texture combinations on the screen. Again, no biggie...but heck, with modern day hardware why suffer like this??? LOL

So point being, I have been meaning to try the monitor's DisplayPort as well, would need to use a DVI to DP connector, etc, but I'm curious how that might pan out?

Hi Paul,

Updated to 5.15.59 - https://smedley.id.au/tmp/uniaud32-linux-5.15.59-20220805.zip

Similar to David's experience, I am not getting no SOUND with the 5.15.59 release...HOWEVER, the 5.15 kernel update does work quite fine and unless it's my ears playing tricks on me, the sound seems to have higher quality??? ugh...???

Seriously...fired up PM123 and went through some of my music (eg Phil Collins' "In the Air Tonight", 251 kb/s VBR, 44.1 kHz, Joint-Stereo) and it literally kicks ass!!!

Thank you!

Thanks Dave, I'll try and investigate over the weekend. I'm also getting a trap with AC97 hardware in VirtualBox.

Paul,

  Not getting any sound out of this one, but it seems to be loading:

I'm using DP out to DP in on the monitor since a while on this system. But I disabled all screen saving software long ago cause it didn't work. When I've the need for power saving (and don't wanted to switch off the whole system) I switch of the monitor with its remote control. Switching on afterwards works with OS/2. But not with Win7. As this simple test does not even work with Win I never tried to test anymore off this stuff.

Screen saver, actually switching monitor power on/off, never worked on this system. It worked on my old system when I patched black10x.zip to write the proper registers of my old ATI300 graphic card. But never on this newer system. Either with integrated (Intel) graphic nor with the PCIe Radeon 550.

that Displayport falls back to a DVI compatible protocol when used with a passive converter.
This is a feature of your motherboard/graphic chip. The signals are different between DP and DVI. Your mobo detects the DVI adapter and tells the graphic chip and the output transmitter to switch signals to DVI standard. That's a feature of some mobos/graphic cards but not mandatory. Your DP output at your mobo emulates DVI signals when you put a passive adapter on that. But it does not make a real fully compatible DVI interface out of it.

forcing a reboot to awaken it.
Maybe it's enough to disconnect the passive adapter and reconnect it again. But as it's an emulated DVI it will work different on different mobo/graphic cards. I think you would need reports from people with exactly the same motherboard.

Hardware / Displayport?
« Last post by Dave Yeo on August 05, 2022, 07:34:37 am »
So this computer I'm using has a Sandybridge/Ivybridge graphics controller with a VGA and a Displayport ports, monitor has VGA and DVI ports and supports 1920x1200 as its native resolution.
For quite a while I was simply using the VGA connection, everything worked fine but slightly blurry.
Then I came across a Displayport to DVI passive connector so I tried that.
While the graphics were sharper, especially text mode, I came across these limitations. The screensaver would put the monitor to sleep but it would not wake up, forcing a reboot to awaken it. Same with SNAP and Panorama. Nothing I tried helped here, worked fine under Linux, which reported a HDMI connection. The other thing was I tried using Xfree86 using the VESA (VBE) driver, it simply did not find a graphics card at all, which was weird. Works fine with the VGA connector and an older Panorama/SNAP, newer ones seem to have done something to support UEFI where switching back to the WPS fails, a bit of drawing and then a full hang.
Just wondering about others experience with Displayport and OS/2. Perhaps a monitor that supports Displayport would be better, it seems that Displayport falls back to a DVI compatible protocol when used with a passive converter.

 Hey Paul,

 Wow... thanks for this! It is working fine here so far:

Hey All,

It's been a while between drinks, but I updated uniaud32 to the 5.15 kernel. I first looked at this almost a year ago, and got lost in trying to implement the missing kernel functionality.

I took a slightly different approach this time, and got a compiled binary, that seems to work in virtualbox. I'll try see if my real hardware works as well over the weekend.

Link is https://smedley.id.au/tmp/uniaud32-linux-5.15-20220805.zip

Next steps will be to get to the current 5.15.x LTS build (5.15.59 at the time of writing)

The 5.15 kernel is a Long Term Support kernel, that has a projected end of life date of October 2023.

Cheers,

Paul
