Re: [Xen-users] XEN sound emulation locks device exclusively

OK, so I have the wrong idea about how XEN handles sound.
(I found no documentation on this, so it was basically a guess.)
Here is what I know:
- In the notebook computer there is and Intel HDA sound card.
- In the configuration file for my HVM guest, I have "soundhw='sb16'".
- The WinXP running as HVM guest sees a Sound Blaster 16 sound device, and can use it.
Here is what I thought:
- Either the XEN hypervisor, or some user-space tool (probably the later) emulates
the hardware interface of a SB16 for the HVM host, and
- it relays the sound to the sound system of DOM0.
If this is not how it goes, then what?
I thought that since there is no real SB16 in the host in question,
the SB16 interface must have been emulated,
but from what you say I seem to be mistaken.
Could someone please explain this, or give a link to the appropriate documentation?
Thank you:
Kristof Csillag
