Afraid I can't really help you with sound, but I may say I use libvirtd/qemu in 9.10, and I have sound from the VM's. You use qemu with what? Two things, again, I'm afraid, obvious :) If by "don't get a working sound" you mean no sound, I'll make sure I have a guest sound device (sure you did) and it may be a configuration issue from the software that connects to the client. You have more than one guest? They all have that problem? What you use to connect (tsclient, rdesktop, ...)? have you tried to connect in diferent ways? Any errors on logs? (/var/log/libvirt/qemu/<vm>.log for me, don't know what for you), messages, syslog... And you may confirm that you do have sound on the machine from where you connect to the VM's, yes? (I would say that the host doesn't even need to have sound, so no problem there, but I'm not sure of it) Regards Luis <div class="gmail_quote">On Sat, Apr 3, 2010 at 12:58 PM, Jose Luis Alarcon Sanchez <<a href="mailto:jlalarcon@inmail24.com">jlalarcon@inmail24.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hello. Into my Ubuntu GNU/Linux 9.10 i use Qemu for emulate others distros and systems. In the previous versions of Ubuntu and Qemu all worked okey, but with Karmic Koala, there is a sound problem that i am not able to solve. The guest systems don't get a working sound. Is it a "known problem"?, anybody has this fail?, anybody knows a solution for this?. Thanks very much, in advance. You are very kind. Regards. Jose. -- Not Registered GNU/Hurd User.
