for always, you can also specify DAC_DEV and ADC_DEV for different sound
cards on your real machine or device null if you have more than one vm
do you mean both alsa or pulseaudio backend were not build in Ubuntu kvm
package ?
static struct audio_option alsa_options[] = {
{
.name = "DAC_SIZE_IN_USEC",
.tag = AUD_OPT_BOOL,
.valp = &conf.size_in_usec_out,
.descr = "DAC period/buffer size in microseconds (otherwise in
frames)"
},
{
.name = "DAC_PERIOD_SIZE",
.tag = AUD_OPT_INT,
.valp = &conf.period_size_out,
.descr = "DAC period size (0 to go with system default)",
.overriddenp = &conf.period_size_out_overridden
},
{
.name = "DAC_BUFFER_SIZE",
.tag = AUD_OPT_INT,
.valp = &conf.buffer_size_out,
.descr = "DAC buffer size (0 to go with system default)",

Title:
no audio in KVM virtual machines : cannot select alsa or pa
Status in “libvirt” package in Ubuntu:
Incomplete
Status in “pulseaudio” package in Ubuntu:
Incomplete
Status in “virt-manager” package in Ubuntu:
Incomplete
Bug description:
I am on Ubuntu 13.10 desktop
16GB ram
asus sabertooth 990fx r2.0 motherboard
amd 8346 cpu
nvidia gtx650 video card
Since upgrading to Ubuntu 13.10 audio no longer works in KVM.
Checking SYSLOG I found this error being logged:
Oct 31 15:32:31 bmullan-virtual-machine pulseaudio[1814]: [alsa-source-ID 21
Analog] alsa-source.c: ALSA woke us up to read new data from the device, but
there was actually nothing to read!
Oct 31 15:32:31 bmullan-virtual-machine pulseaudio[1814]: [alsa-source-ID 21
Analog] alsa-source.c: Most likely this is a bug in the ALSA driver
'snd_hda_intel'. Please report this issue to the ALSA developers.
Oct 31 15:32:31 bmullan-virtual-machine pulseaudio[1814]: [alsa-source-ID 21
Analog] alsa-source.c: We were woken up with POLLIN set -- however a subsequent
snd_pcm_avail() returned 0 or another value < min_avail.
