Sound in VMWare

[emr <ernst.rohlicek@inode.at>]

Hi, I got 9front up for testing :-)

I cant get audio working, though:

"rc: play cannot open /dev/audio: mounted directory forbids creation"

... meaning there is no /dev/audio device.

The 9front wiki lists AC97 on the features list (
http://code.google.com/p/plan9front/wiki/features ), but it seems like
the device and vendor ID of the card created by VMWare is not known to
plan9/9front.

This is the card created by VMWare Workstation 7.1:

test@ubuntu:~$ lspci -s 02:02.0 -v -nn
02:02.0 Multimedia audio controller [0401]: Ensoniq ES1371
[AudioPCI-97] [1274:1371] (rev 02)
	Subsystem: Ensoniq Creative Sound Blaster AudioPCI64V, AudioPCI128
[1274:1371]
	Flags: bus master, medium devsel, latency 64, IRQ 16
	I/O ports at 2080 [size=64]
	Kernel driver in use: ENS1371
	Kernel modules: snd-ens1371

With the es1371 / ac97 chip, I get the speaker symbol from VMWare turn
to green, but kernel output shows no audio chip detected.

Please add this device ID to the relevant source files (unless they
are already there, but I am doing it wrong).

I tried changing the virtual audio device in VMWare by editing
the .vmx file:

  sound.virtualDev = "hdaudio"

instead of the default

  sound.virtualDev = "es1371"

but still I receive same error message in plan9/9front. This is the
Intel HDA device created by VMWare:

test@ubuntu:~$ lspci -s 02:02.0 -v -nn
02:02.0 Audio device [0403]: Intel Corporation 631xESB/632xESB High
Definition Audio Controller [8086:269a] (rev 02)
	Flags: bus master, fast devsel, latency 64, IRQ 16
	Memory at d8900000 (32-bit, non-prefetchable) [size=16K]
	Kernel driver in use: HDA Intel
	Kernel modules: snd-hda-intel

With HDA device, the VMWare speaker symbol does not show or turn to
green. Interestingly, the plan9 kernel shows "#A0: hda codec" etc.
Still same error message, though when trying to run "play
somesong.mp3".

Under virtual Linux, both device types work and I can play sound fine.

Any way to get these two cards working?
