P_rzola Posted September 2, 2018 Share Posted September 2, 2018 I'm using Nokia 8 (TA-1012) with "LG hi-fi plus afd-1200 with b&o play" external hi-fi DAC. When I boost bass, I think Poweramp doesn't limits the sound, and audio output sounds like explosion. Notes: * I'm connecting hi-fi DAC to my Nokia 8 via USB type-c port (my phone has a 3.5 mm jack output but i don't use it) * There is no such issue at v2 with the same configuration. * The older build of v3 has this issue too. Correction: I'm experiencing this issue when these bars exceeds their limits. Link to comment Share on other sites More sharing options...
andrewilley Posted September 2, 2018 Share Posted September 2, 2018 Try lowering the pre-amp gain a bit, although there ought to be enough headroom anyway if you are using 24-bit output. Andre Link to comment Share on other sites More sharing options...
P_rzola Posted September 2, 2018 Author Share Posted September 2, 2018 @andrewilley thanks for the reply. My Hi-Fi DAC is 32 bits and It has ES9028C2M + Sabre9602C chipset. I experienced some weirdness when I'm doing what you recommended. When the volume is 97% or higher, there is no blowing effect in the sound, no matter what the value of the pre-amp gain. When I lower the volume to 96% or lower, the sound starts to blow immediately and I can only correct it with lowering the pre-amp to very low levels, and the volume of the sound becomes very low. There is no such problem when I use my headphone jack. Link to comment Share on other sites More sharing options...
P_rzola Posted September 8, 2018 Author Share Posted September 8, 2018 update: after enabling usb dac setting at settings > audio > output > hi-res output the problem was solved. but i have a new problem now: in that menu, sample format is shown as 24-bit, but i have a 32 bit dac? how do i change the sample rate?
