Androd -> MacOS - Audio garbled after first connection, Android app software error and force close (sometimes)

[larryqiann]

Bug Description

When a macOS host is set to stream audio from a device and a session is started, the audio is played normally on the receiving Android phone. After about ten seconds, the Android app will either crash and force close, or the connection will fail with a "software error". (sometimes)

When the connection is recreated, the audio has extreme distortion and noise (sounds like electrical arc welding), and the session will close or there will be a software error on the Android side within a 20 seconds. (sometimes)

This problem is only experienced when there is audio playing on the macOS host device.

Restarting the Rust Desk remote (server) side will reset the audio for the next session.

How to Reproduce

1. Install latest (as of filing) nightlies on both Android phone and the macOS device
2. Set up audio device for sound on host macOS device
3. Make a connection to the Android device and play audio on the macOS device
4. Observe the sound operating normally
5. Disconnect the session
6. Reestablish the session
7. Play audio on the remote macOS device
8. Observe error
9. Restart the macOS Rustdesk software and reattempt the test, observe that the audio is normal for one session again

Expected Behavior

When the client is connected to the server, both the first and subsequent times, the connection will be stable and audio will be transferred without noise or distortion in a stable way

Not sure if it is related to my upgrade to latest osx, I do not see this before, only see this after upgrade to latest osx 14.3.1

The last time I tested this was in Ventura, last year in around June-July. I don't remember if I opened an issue about it, but the problem is the same.

It sounds like to me that there is some lag in getting the samples all played out. During the garbled sound, the latency slowly gets longer and longer, and there is at least several seconds of garbled audio for every second of input audio.
