Describe the bug
No sound coming out when the "External Headphones" is selected. There is a high chance this is related to the #325 issue.

Wether you start eqMac with music playing or not, music app running or not, external headphones plugged in or not, once you start playing music using an external headphones no sound is coming out.

Steps to Reproduce
Steps to reproduce the behaviour (feel free to change the placeholder as you need):

1. Make sure no music/audio is running
2. Close all music/audio playing apps
3. Start eqMac
4. Plug your external headphones
5. Start your music (Spotify for me)
6. Play your music
7. No sound coming out of the headphones
8. Quit eqMac
9. Sound is now playing in the headphones

Expected behaviour
Audio should play using external headphones.

Setup information:

• Audio device used for playback: External Headphones
• Audio transmission interface:3.5mm Jack
• macOS Version: 10.15.5
• eqMac Version 0.3.2
• eqMac UI Version 1.2.0
• eqMac Driver Version 1.1.1

Additional information
Possible related to #325

Tested in older version, no sound issues with external headphones with v0.3.0 and v0.3.1 (while I was testing installation issues see #325)

[AcidSlide]

After installing again v0.3.2 (without going through uninstall of v0.3.1), confirmed NO SOUND using External Headphones.

So I guess it works v0.3.1 and below but not on the latest release.

@AcidSlide I had a similar issue. If you open up Midi and switch the format of your headphones and eqMac from 48000Hz to 44100Hz do you get sound through eqmac again? Not sure why, but that worked for me.

@Rugroden i'll try that later, but I need to reset my copy of the source code first, I think I broke it while trying to trace the sound issue ahahaha

[AcidSlide]

@Rugroden WOAH!! It worked.. switching to 44.1khz made it work

@nodeful it actually worked switching it to 44.1khz, by the way i'm using the 'development' branch, tried the 'driver-improvement' branch but gave me too much errors ahahaha

[Rugroden]

Glad that worked for you! Occasionally with this (for me anyway) the sound will start to fuzz out for like 2 seconds but then it figures itself out with no intervention from me and it's fine. I'd be interested to know if you run into that as well @AcidSlide

[nodeful]

Sorry I haven't looked into the issue thoroughly yet, as very busy with my job this week. Glad you resolved it by playing with Sampling Rate, I won't close the issue so other people can reference. Yeah the driver-improvement branch is work in progress at the moment.

[AcidSlide]

No problem @nodeful I just hope it also get addressed in the new driver-improvement that you are doing. I would like to keep the bit rate to 48k if possible but for now manually switching to 44.1k from time to time is doable.

@AcidSlide Thank you for figuring out it works on 0.3.1! Was reading through all the issues on this repo (as well as in eqmac2 -- confusing that v3 is just called eqmac), and was able to get it working in 10 seconds just by installing 0.3.1. For me that's a better fix than switching to 44.1k
