<div dir="ltr">I'm of no help wrt getting PulseAudio working. However, how important is this to you? A much better solution for me (I use the VM exclusively for gaming) was to get a $10 PCI USB card, and some USB headphones. I pass the PCI USB card through to the guest, and everything works better this way. Surround sound, no crackling, etc. Perhaps this would be a better solution for you too. </div><div class="gmail_extra"> <div class="gmail_quote">On Fri, Jan 8, 2016 at 10:01 AM, sL1pKn07 SpinFlo <<a href="mailto:sl1pkn07@gmail.com" target="_blank">sl1pkn07@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="HOEnZb"><div class="h5">2016-01-08 17:50 GMT+01:00 Feadurn <<a href="mailto:feadurn@gmail.com">feadurn@gmail.com</a>>: > I did the export in the bash, check it was activate with set, then launch > virt-manager and launch the vm from there but still the same issue (exact > same error) > > Regards, > > Feadurn > > > On 08/01/16 16:07, sL1pKn07 SpinFlo wrote: >> >> 2016-01-08 16:45 GMT+01:00 Feadurn <<a href="mailto:feadurn@gmail.com">feadurn@gmail.com</a>>: >>> >>> I have everything working except the sound from the guest.
