Yes indeed, it was a 754. The later PCG-SRs (beyond SR9) are YMF754 machines, not 744. […]Brute389 wrote on 2021-04-01, 08:13:
In talking with him prior to this, he indeed does have a ymf754. I have the same sound chip in my C1VJ, and it plays out exactly as he describes. I used setupds 3.16 and even 3.17 to try to get it to work and it would only come back with 8 bit sound. I have been looking around on old sites and recovery discs for Sony vxd drivers for the 754, but I don't believe any official ones were made as wdm drivers became mainstay. It indeed seems like a modded pack needs to be made. I was wondering if maybe the wdm drivers could be installed first then slipstream the vxd drivers to trick the system?

I don't think the issue is the driver version per-se, since the VxD drivers that you have and the one for Phil's should support the 744s and 754s. I also got the audio working on Windows...once, but that was in the middle of me installing some other missing things...and somehow the config stabilized and the ability went away. I also know that the hardware is functional since I still have the original HDD with a working Win2K install (which came with the original Japanese Windows 2000 driver pack, plus the SR31k recovery disk ISO is on archive.org).
As Brute389 would've put it, there were no VxD drivers available from Sony in question, but I think the issue goes beyond simply the audio drivers. I think we need to initialize the other hardware in the machine so the resources are bumped into place correctly. Once that's done the hardware "should" work. The missing drivers are the ones for the Sony Programmable I/O controller (sonyPI), the Conexant WinModem and maybe the magicGate memory stick controller - like I've said, most of those missing drivers should be in the recovery image/driver archive for the SR1BP, which is one of the first in the series and runs Win98SE natively. it obviously doesn't help that Sony pulled the drivers back in 2017, and there's only a 455GB, multi-part driver set for vaio-link.com on archive.org that is not well documented.
I do not know how much it will help you, but I can upload the restore disks for my C1VJ to archive. It seems Sony laptops in this era all shared similar hardware and drivers, and I have all of those drivers you mentioned on those cds. As for you cyclone3d, the drivers on the cd are for windows ME if you are interested in them too.
