Dear Community, I've been using piCore Player on a new Pi 2 model B, taking data via wired ethernet and feeding a Marantz SA8005. Everything works great via hifiberry digi+ w/ toslink, through 24/192. I have trouble using the coax spdif, w/ no sound when using a wall wart and some sound but w/ dropouts using a Jerome linear power supply I used to use for my Touch, so I guess the coax issue is power-related but anyway that's not why I'm writing.
When using USB, I occasionally get a horrific loud continuous white-noisy kind of continuous hissing static. Sometimes I can tell when it's about to start - the music starts to "tear" or "spit" and I know "oh crap here it comes". Sometime it plays OK for hours but I never know when I'll get blasted. I've tried a few different USB cables -no difference. The static seems to happen more frequently when I switch tracks. Happens on 16/44 w/ or w/out upsampling as well as w/ higher-rez either upsampled or not. Thinking this may be a buffering issue I added buffering to the Buffer Size Settings tab (tried 40000:4000, I think). I thought this fixed it but then it came back. I noticed that when I turned the volume all the way to 0, via a Duet controller, that the hissing stopped, and came back full volume when the volume was set to 1 out of 100%. Sometimes I hear music playing through the static and even at volume level 1 out ouf 100% this music plays at full volume. Thinking that the whole static issue is somehow related to the volume control I disabled it but the static still comes back. So I don't use the USB anymore which means no DSD. I'm left thinking that this may be a quirk of the Marantz, where it sometimes loses the USB connection and responds with a full-volume blast of white noise. Very unpleasant as you can imagine. Any ideas? Any hints? Better yet any solutions? I installed the piCore 2.0 and same problem. One thing I didn't try was to remove the digi+ to see if it has any impact on the USB. I'll try to borrow another USB dac so I can check out this issue and the coax issue as well. Thanks in advance for any assistance! (although my setup does still sound great through the toslik!) -Mike ------------------------------------------------------------------------ mfsoa's Profile: http://forums.slimdevices.com/member.php?userid=65172 View this thread: http://forums.slimdevices.com/showthread.php?t=97803 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
