Feature request: option to select the audio device

1. Please provide the freerdp-like option to explicitly specify the audio device to work with, if more than one is installed. For example, a built-in audio card and a USB-headset or camera.

Apparently the current latest client provides no control over audio device to use. If I plug in a USB-headset and even make it default, the client still chooses the internal audio (probably the first device it can enumerate).

2. It would also be useful to give a choice of sound API. ALSA is more responsive and has lower latencies, so I would prefer using ALSA for sound redirection if both ALSA and Pulse Audio are installed.

The test setup is: Linux Client 16.2.0 x86; Ubuntu x86 16.04 LTS, 14.04 LTS, 12.04 LTS; Inel HDA, Logitech USB-Headset, Logitech HD Webcam with Microphone.

 

Hi Dmitro, may ask you to provide us with a log from your client device?

1. enable extended logging first
2. perform the steps reproducing the issue
3. get the log here: ~/.config/2X/Client/ClientLog.log
