[Asterisk-Users] Asterisk 1.2.6, VMWare, & Playback/Background GSM prompts

[dveith1 at comcast.net]

I've spent the past week experimenting with Asterisk at Home 2.6, and
then Asterisk 1.2.6 individually, on VMWare Workstation 5.5. I have an
entirely IP (hard & soft)phone setup (IAX and SIP) so I have no
requirements to support any Digium PCI cards, etc.

All in Asterisk works extremely well except for one thing: Playback of
sounds (GSM format) such as an ivr greetings, sound terrible. Choppy,
uneven, broken audio, etc to the caller.

I have a fairly fast system as the host: dual core AMD X2, 2GB mem,
running SMP 64-bit centos-4.2. Asterisk guest OS is centos-4.2 32bit.
No other guests are running.

Just for grins, I also installed Asterisk on a lowly 3-year old AMD
Duron system (no VMWare). Using the same Asterisk config files and
sound files as above, but in this case the audio playback (using the
Asterisk 'background"' command) sounds perfect.

Anyone else notice this when using Asterisk with VMWare
Ideas?
