Description Michel Smidt univentionstaff 2014-03-03 16:21:01 CET
Occured in a customer project: Ticket#: 2014021021003427

On a Acer Veriton N2110G the sounddevice is not recognized in the Citrix XenApp-Session by default. After starting manually pulseaudio on the thinclient the sounddevice is recognized.

The problem probably occurs due to the special hardware.

Check with UCC 2.0 (which will have new drivers etc)

It's currently uncleae whether this thin client will be used at the customer, wait a bit.
Comment 3 Felix Botner univentionstaff 2014-05-21 17:10:00 CEST
OK, added 

+if is_ucr_true 'citrix/pulseaudio'; then
+    pulseaudio &

to the xenapp session script, sound works on Acer N2110G if 'citrix/pulseaudio=yes is set.
Comment 4 Erik Damrose univentionstaff 2014-05-22 16:31:23 CEST
Verified: If the UCRV is set, sound plays fine with the Acer thinclient.
