export QEMU_AUDIO_DRV=alsa qemu-system-x86_64 \ -cpu host \ -enable-kvm \ -smp cores=4 \ -m 4G \ -drive file=disk.qcow2 \ -soundhw ac97. I've had to use the AC97 sound card due to the fact that it is one of two cards recognized by Windows 7, and the other one, HDA, yields even worse quality than AC97 (I'm using the AC97 driver from the RealTek website, as …

Qemu audio. 参考一 参考二 参考三. 最近由于项目需要，研究了一下qemu audio。Guest调用Qemu的虚拟声卡设备，声音数据（PCM）传到Qemu后，Qemu再传给事先搭建好的后端接口，这些后端接口都是通过一些环境变量设置的，如果VM使用的是spice协议，默认会添加这个环境变量：QEMU_AUDIO_DRV=spice，音频数据通过spice ...

https://askubuntu.com/questions/719819/libvirt-configure-guest-to-share-host-audio
export QEMU_AUDIO_DRV=pa Doing this gave me the desired effect and the guest audio would run smoothly but the host audio would not work until I would have closed the guest. Looking at the host processes I noticed that libvirt spawned another Pulseaudio instance under my current user (effectively having 2 Pulseaudio instances) instead of using ...

audio: Failed to create voice `es1370.adc'. Of course befoure starting the vm, I issue: Code: export QEMU_AUDIO_DRV=sdl. export QEMU_SDL_SAMPLES=2048. Then I tried with alsa, either with es1370 and ac97. Here is the output for ac97 (that one for es1370 is the same fashion): Code: alsa: Could not initialize ADC.

First you need to switch Qemu to use AC97, for the soundhw option use ac97 i.e. -soundhw ac97 and also set QEMU_AUDIO_DRV to alsa (I also am setting the QEMU_PA_SAMPLES to 128 and not sure if that will affect things or not) QEMU_PA_SAMPLES=128 QEMU_AUDIO_DRV=alsa

I have tested this on Linux. (For windows checkout comments or @Tekk answer) If you don't want audio simply use: export QEMU_AUDIO_DRV=none && emulator -avd Nexus_4 . TL;DR. Quote from here. Based on some digging around, it looks like QEMU2 removed the ability to completely disabled audio - you can specify which sound card the audio goes through, but can't turn it off …

Based on some digging around, it looks like QEMU2 removed the ability to completely disabled audio - you can specify which sound card the audio goes through, but can't turn it off altogether. The "-audio" flag was replaced with "-soundhw", which lets us specify …
