Hi. I installed Win95 OSR2 on the Asus P8H61-M LE R2 motherboard. There is one PCI slot in which I use the Sound Blaster Live! sound card (CT4830).
I installed drivers from the Live! Install CD.iso that I downloaded from this forum:

Sometimes I have a problem that at the start of the Win95 system, the sound stuck like a video:

A similar situation is when watching DivX or MP4 video in VLC 0.8.6f and also when playing MIDI files, e.g. on an external MIDI device. I note that this happens only sometimes.
I tried other drivers but there is the same problem.
When the problem appears, I have to reset the computer several times using RESET button on case and it often helps.

So that is on interrupt 11, check in the resources view to see if anything else is on 11.
If the COM and LPT are enabled, disabled then in BIOS and that may reshuffle the resources

IRQ11 is used also by integrated graphics card iGPU, IRQ Holder and some PCI bridges:

    IRQ 11                       Shared                VBE Miniport - Standard PCI Graphics Adapter (VGA)
IRQ 11 Shared Creative SB Live! Value
IRQ 11 Shared IRQ Holder for PCI Steering
IRQ 11 Shared Mostek standardu PCI do PCI-do-PCI
IRQ 11 Shared Mostek standardu PCI do PCI-do-PCI
IRQ 11 Shared Mostek standardu PCI do PCI-do-PCI
IRQ 11 Shared Mostek standardu PCI do PCI-do-PCI

I tried to disable USB, COM and LPT in bios but Win95 still detects these devices - probably because the bios settings do not affect in CSM (Legacy) mode and work only in UEFI mode.

If sound probelm appears while start Win95 then possible mute sound and OS still works.
If sound problem appears while playback MIDI then OS hangs.

P.S. The same sound card works OK in WinXP 32-bit or WinXP 64-bit on this motherboard.

H61 chipset doesn't have native PCI ports, perhaps the issue is in ASMedia PCIe-PCI bridge.
