Hi. I have shairport sync setup on a ropieee endpoint using USB output and software volume control, using a Topping E30 DAC. I can barely hear sound, when using Tidal Airplay to the device, even with max volume on my apple device. The DAC works fine with Roon using rhe same endpoint, but not airplay. I also have no problems airplaying to another ropieee endpoint using a schiit dac.
Any advice? Is the E30 not compatible somehow?
Thanks!
