Hate to bump this thread but could anyone of you SV2GX4 owners check whether your board works with a POD and a GUS (Max or PnP) for Duke3D/ROTT/Raptor? Duke and Rott have issues with Midi, while sounds work fine. With Raptor it's the other way around.
I have a SV2GX4 Rev 1.7 here which butchers the sound for above games whenever I try to use the GUS with my POD83 - so far the only fix I found was disabling L1 cache altogether.
Also noted that CTChip hangs when attempting to fix the dirty-bit whenever I have 1024K L2 cache installed - however it works fine with 256K in place. I'll check the modified BIOS later today.
I don’t have a GUS but I’ve had issues getting sound effects working with Duke3D when I have a POD installed on the GX4. I’ve tried a SB32PNP, Awe64, and an ESS. All three will lock up my machine when trying the sound test. If I install an AMD 5x86, all else being equal, sound effects work fine. I think our issues are related. Are you using Feipoa’s bios or original Asus bios? I’m using Feipoa’s myself.
Update: disabling L1 cache also resolved the sound issue for me, obviously not ideal 🤣
Update 2: Moved jumper 21 to position 2-3 for L1 WT and set L1 to WT in the bios and this resolved my issue. You lose the WB performance boost but it’s much better than disabling L1 altogether. Thinking about adding a toggle for this. Please try it and let me know!
