Neither QEMU nor KVM (with its in-kernel handling of the involved timer chip) translates the guest's speaker settings into anything audible. But that should be feasible. For KVM's in-kernel handling some new interface would have to be established, for QEMU it should even be simpler. It just takes someone with time and motivation to dig into this. >=20 > The environment variable QEMU_AUDIO_DRV=3Dalsa is set and I run KVM wit= h > the option -soundhw all. You may succeed with this approach when redirecting the guest's console beep to the sound card of your virtual machine. There is http://www.carcosa.net/jason/software/beep which claims to do that, but I never tried. >=20 > Thank you very much for your help in advance. >=20 > Simon > Website: >=20 Jan --------------enig42B46642CDD76E080488D1D0 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAknwHJEACgkQniDOoMHTA+nO/wCeIHmPm6qb0WyicS3A4a1epkvl 08MAnR9gcqdNNZ7ikTQIootsmhzli8tA =EZka -----END PGP SIGNATURE----- --------------enig42B46642CDD76E080488D1D0--
