Howto enable network sound from domU to dom0?

[Mark Weinem <mark.weinem%onlinehome.de@localhost>]

Hi,

I'm running Xen2 with NetBSD-3, it's the"standard installation" from the 
NetBSD/Xen-HowTo. Esound and xmms-esound are packages from pkgsrc-2006Q1, 
without modifications 

I don't get sound output (from domU to dom0) running with esound/esd.

The dom0 has esd running: 

        esd -tcp -public -port 16001


The domU's bash gets: 

        export ESPEAKER=192.168.1.10:16001       


Esound is installed on dom0 and domU. Xmms-esound on domU is configured 
for eSound, remote host, 192.168.1.10 and port: 16001. The error messages 
advise to check the correct configuration of the soundcard....

The Soundcard is:

eap0 at pci0 dev 12 function 0: Ensoniq CT5880 CT5880-C (rev. 0x02)
eap0: interrupting at irq 11, event channel 6
eap0: ac97: TriTech TR28602 codec; no 3D stereo
audio0 at eap0: full duplex, mmap, independent
midi0 at eap0: AudioPCI MIDI UAR


Sound works on dom0 with xmms-esound and remote-host disabled.
But it also fails with remote-host enabled, 192.169.1.10 (or: localhost) 
and port 16001. 

Are there any netsound issues with NetBSD, Xen or the NetBSD/Xen Kernels?

Many thanks & greetings, Mark Weinem
