@LordZeref have you checked the audio settings while a video is playing(not in ptvl) to see if 'Enable Pass through' is on? If it is, disable it and 'set as default for all videos'.

yep, ive looked into all the audio settings. i seen that was there, but it was not enabled. ive tried even enabling it and disabling it. still nothing.

I was going to suggest ptvl was possibly muting kodi, but you said you can see the volume bar in windows audio mixer. BTW the default playback device in windows has no affect on what is selected in kodi(I have mine set to toslink in windows and hdmi in kodi). If this only happens after ptvl is installed, then you should create a log and post it for Lunatixz.
