I have an OPPO Ha-2 headphone dac amp connected via USB (connected out to headphones) on Windows 10. In OBS, the sound level shows as normal on the LED meter (and I hear the sound normally through the headphones), like any other audio output, but when streaming or recording, the actual audio sound level is very low, which just isnt right. It doesn't match with the OBS sound meter levels. Ive tried several things but cannot see why this is happening. Using an Astro Mix Amp doesn't have that problem. Any advice would be appreciated to correct this.
