[Q] Headphone jack output topic

So I've noticed that my LG G2 D801 has a lot lower output signal strength than the other phones I've had.. Like my buddy plugs his phone into my car after my phone was plugged in (I am a bit of an audiophile my car has a ~2000$ aftermarket sound system) and I have to turn down the volume significantly. He has an S5. I've learned that the stronger the original output signal the better quality the sound. So here's the scoop. Does the output strength vary with the phone or with the ROM or with the kernel and is there a way I can then it up?

[Q] Tasker Help - Toggle Headphone Output topic

I just replaced my 3.5mm jack on my VZ HTC M8 however the phone does not recognize when the headphones are inserted. I've tried multiple headphones to no avail. The audio jack is however working after using the app SoundAbout to force headphone output.

I would like to use Tasker if possible to force headphone output only when Spotify launches. Is this possible? I know the SoundAbout app has a widget toggle for the home screen but I would really like to automate this process.

Thanks for any help.
