Soft-fail when no audio available

##Description
When no audio devices or drivers are installed, the program intercepts the connection handshake, leading to a disconnection. The issue can be resolved by installing the necessary audio drivers and connecting a pair of headphones. This unexpected behavior occurs even when the program does not explicitly rely on audio functionality.

##Steps to Reproduce
Ensure no audio drivers are installed on the system, and no headphones or speakers are plugged in.
Attempt to start the program and initiate a connection.
Observe that the connection fails due to the intercepted handshake.
##Expected Behavior
The program should allow the connection to proceed normally, regardless of whether audio devices or drivers are installed, or at least provide a more informative error message explaining that audio drivers or devices are required for the program to function correctly.

##Actual Behavior
The program interrupts the connection handshake when no audio devices are detected, causing an immediate disconnection. No clear error message is provided to indicate the lack of audio drivers as the root cause.
