To enable sound manually I found I needed to do three things: 1) export QEMU_AUDIO_DRV=alsa (otherwise it defaults to oss, which is not available by default on my Ubuntu system) 2) Add qemuparams="-soundhw all" to runqemu command line (you can select drivers more specifically, but given there are only three supported drivers I don't think it matters) 3) modprobe snd-ens1370 within the running system - apparently we already install the appropriate kernel module, we just need to auto-load it. 17216 1 280 richard.purdie 2011-11-15 13:28:04 +0000 Created attachment 280 Patch 1 to enable sound 17217 2 281 richard.purdie 2011-11-15 13:28:31 +0000 Created attachment 281 Patch 2 to enable sound 17218 3 richard.purdie 2011-11-15 13:30:19 +0000 I tried this (patches attached). I ran into the complexity of my system running pulseaudio. To make this work we'd need to enable pulseaudio in qemu-native/nativesdk by building pulseaudio as a dependency for qemu. We could really use a way to turn these features on/off in the qemu script. 17220 4 bluelightning 2011-11-15 14:23:08 +0000 Surely you don't *need* pulseaudio support in an application just to play sound with it installed? I was under the impression it provided a standard ALSA interface. 17222 5 richard.purdie 2011-11-15 15:26:30 +0000 Running qemu complained my alsa device was locked, presumably by pulseaudio which was active on the system. Qemu also has a pulseaudio specific backend... 41548 6 cristian.iorga 2014-03-20 15:19:15 +0000 Using pulseaudio as the audio backend for qemu works, however, it is my understanding that not all Linux distros rely on pulseaudio server for audio services. This would basically mean, at a minimal level, to detect at runtime (runqemu) which audio server is used (pa, alsa, oss) and set qccordingly qemu. Another issue that needs to get solved is that sound from guest machines is muted while using qemu's pulseaudio backend. This also needs to get fixed. Finally, a little bit of cleanup needs to be performed in qemu scripts (runqemu). 44887 7 sjolley.yp.pm 2014-07-31 15:26:23 +0000 *** Bug 5602 has been marked as a duplicate of this bug. *** 66181 8 liezhi.yang 2016-09-15 04:17:43 +0000 Now the audio support is controlled by bsp, it can set QB_AUDIO_DRV, QB_AUDIO_DRV and QB_AUDIO_OPT, see meta/classes/qemuboot.bbclass for more info.
