I too have this issue, and I can only have 16bit/48kHz output, though I have 32bit/96kHz enabled on my device. The most funny part is, when I search in this forum, someone said all I have to do is to reach my manufacture because I'm using a custom rom, hah..
What? All problems with custom roms needed to be reported to their devs? That's really a good answer & good solution ? Well Newbie, I think you could try to change some output settings first to bring the sound out, though this will causes some lost, we have no choice right this moment, have we?
