Status in QEMU: Fix Released Bug description: = I have built [both] current git, and 4.2.0, there are issues with audio/s= oundhw for both. Specifics: Linux nullrig 5.3.0-24-generic #26-Ubuntu SMP Thu Nov 14 01:33:18 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux Out of source build, successful for both: ../configure --prefix=3D/opt/qemu --target-list=3Di386-softmmu,mips64el- softmmu ---enable-sdl --enable-sdl-image --enable-lzo --enable-bzip2 --enable-avx2 --enable-kvm --enable-membarrier --enable-plugin Call: ./qemu -machine pc,accel=3Dkvm,usb=3Doff -cpu pentium -m 64 -rtc base=3Dlocaltime -parallel none -soundhw sb16,adlib,pcspk -device cirrus-vga,bus=3Dpci.0 -drive id=3Ddisk1,file=3Ddoom.cow,format=3Dqcow2,if=3Dvirtio -audiodev pa,id=3Dpa Audio for sb16 sounds ok, however if i switch to a timer based audio: -audiodev wav The output is wrong.. I had assumed it was all timer based audio, however it seems to be limited to sb16. So I then tried the next popular/compatible audio device for dos games: gravis ultrasound [gus]. I get no output at all for it. I have tried more than one piece of software, DOOM shareware is any easy= example. I realize there are better solutions for playing DOS games, however I am interested in snapshot support which many of them lack. I am willing to put the work into fixing it myself if need be, however i'm not very familiar with the audio backend. Specifically, it is already mixed into a single buffer, if 'adlib' driver is already working: (audio_pcm_ops.write() output is correct on timer based output) I failed to see how it affects emulation of the sound blaster.
