VB 6.1.16
host: macOS 10.12.latest
guest: ubuntu 20.04 LTE
guest uses ICH AC97 audio controller and host CoreAudio.
Proceeding in following way
Guest was started while on host-side only build-in (internal) audio input/output devices were active.
During guest is in operation further audio input/output devices are attached to host and activated - bluetooth headset.
Guest audio source still plays through host standard input/output.
Guest restart is needed in order for guest audio to use bluetooth headset.
Is this VB issue or rather of host operating system one?
If an issue of VB is it the how VB is implemented? If not what might be resolution?
