Thin-client :
IP address: dhcp 192.168.2.250
Output of "pulseaudio -vv", though visible on the terminal can't be redirected
to any file.
However, the output upon starting padevchooser is :(manually typed)

Once again to clarify - I am able to connect and use the sound devices
on the thin-client from either side but am unable to connect to the
ltsp-server/image host's sound devices from the thin-client.

Does the ltsp image also need to have the avahi daemon running as is
necessary for the lstp image host? I noticed that the padevchooser
refuses to work if avahi is down.

The config files on the ltsp-server host as well as the ltsp-image are
attached herein.

Thanks & Regards,
SB
