Audio not supported in IronRDP client

[ahmad201494]

I have successfully built IronRDP v0.7.3 and when running the ironrdp-client, the RDP session opens without audio support. The audio functionality does not seem to be working within the session. Could you please investigate and provide a solution or guidance on how to enable audio support in the RDP session?

[CBenoit]

I initially thought maybe your platform was not supported, but audio is supposed to work for all the major platforms via the CPAL backend which should be enabled by default. Can you try to set the environment variable IRONRDP_LOG to debug and run again ironrdp-client?

Here is how you could do that in PowerShell:

$Env:IRONRDP_LOG = 'debug'
ironrdp-client <params>

Or, for bash:

IRONRDP_LOG=debug ironrdp-client <params>

Feel free to redirect the output into a file that you could upload here.

Also let us know which platform you are using, please.

Also cc'ing @elmarco because I believe he’s more familiar than myself on RDPSND and CPAL.

I don’t see anything suspicious. Do you have more logs you could show us, after the connection sequence?

Can you check if the Windows Audio service is started on the target server?

Also, can you confirm us which platform you are trying to run IronRDP on?
