Audio always set to 48 kHz [Mac] / Audio Configuration

[verstaerkermusic]

when i start mrv2 it always sets the audio playbackrate to 48 kHz - wich can be a bit annoying as i work with Audiosoftware often simultaneously

so i'd like to be able to configure Audio

1. to use/not use audio at all (or only use it when i actually playback videos with audio)
2. if a certain sample-playbackrate should be set or not (most apps that playback video doesnt require a specific samplerate and therefore not request a change)
3. wich soundcard to use and ideally wich channels or just use whats setup in macOs

@verstaerkermusic I did not forget about your request, but only had until now to investigate it.

1. to use/not use audio at all (or only use it when i actually playback videos with audio)

This can be done in any version of mrv2 if you click on the "Audio/Mute" icon in the timeline; you exit mrv2 and open it again (it should open with the Audio/Mute icon set to Mute). Report if this does not work for you. I should probably move the setting to the new Window->Preference->Audio section,

2. if a certain sample-playbackrate should be set or not (most apps that playback video doesnt require a specific samplerate and therefore not request a change)

AFAIK, this cannot currently be done, as we need to set the sample rate to the highest value to play .otio movies, which may mix sample rates during playback.

3. wich soundcard to use and ideally wich channels or just use whats setup in macOs

I've added this functionality in beta of v1.1.8. You can download the beta from:

https://sourceforge.net/projects/mrv2/files/beta/

To try it, you should go to:

Window->Preferences

and then select:

Audio, Output Device.

I tested it with my earphones and with my MacBook Pro speakers, as I don't have multiple audio cards on my Mac.
Please, can you give it a try and report back if it works for you or there are issues?
