Hey guys I've an annoying situation here and I'd dearly love if anyone could shine some light on it!
I've recently put a good bit of time and money into assembling a computer audio system based around a Raspberry Pi 3 (with external hard drive), a Schiit Modi Multibit, Valhalla 2 and Senn HD650s. My problem is I have consistently gotten crackles and pops through this system and have been unable to get rid of them. I've tried 3 different distros (Runeaudio+OpenElec as a dual boot on one SD card, and Volumino 2 on a different one) and all three have had the same problem.
I've followed several instructions on various forums about disabling the onboard wifi, updating firmwares, bootloaders etc. Anything I can find to do with audio crackles I've probably tried. I've bought at 3A power supply to ensure there's enough juice for everything. But no change. Constant popping to the point where I find it unlistenable. And it's definitely coming from the Pi as I've plugged the gear into my Windows laptop and it's completely silent. It's driving me nuts!
I'm considering trying a Digi+ and S/PDIF but I'm reluctant to throw any more money at this unless I know it can be sorted.
Anyone got any further ideas?
