- Improve linux audio support
Does anyone know what's needed yet?
What springs to mind is that when running the existing net/citrix_ica
package (or any update of it that will run under current levels of Linux
emulation), it negotiates a very low bit (8k) rate even when told to use
the best it can. I assume that it is relying on undefined behaviour from
some of the ioctls it is using. For instance, when you perform mixer
operations from within a remote desktop sessoin it does them on the audio
devices, not mixer. This used to return an error which then killed audio
for the remainder of the session. Many years ago, I made it so that mixer
operations would fall though and complete successfully (can't find the
commit now).
So probably just requires tracing the syscalls and seeing what is
requested and returned.
