QEMU Regression with Ensoniq AudioPCI ES1370
Posted: Tue Dec 30, 2025 8:05 pm
There seems to be a some kind of regression on the current upstream branch of QEMU as of writing, where the Ensoniq/Creative AudioPCI 128 (ES1370) emulation seems to be broken on Windows NT 4.0. (albeit unknown for other operating systems, haven't tried)
CLI command:
The lazy approach to fix the issue would be to get QEMU builds as new as 2015 (as confirmed working on "qemu w64 20150115") where the issue doesn't seem to be happening, implying that the regression happened sometime after that.
Of course, that the proper solution would be to go around and properly bisect what has gone wrong, but we don't do that here.
CLI command:
Code: Select all
qemu-system-i386 -cpu pentium -m 512 -boot c -drive file=nt4.qcow2,if=ide,format=qcow2 -vga cirrus -device ES1370Of course, that the proper solution would be to go around and properly bisect what has gone wrong, but we don't do that here.
