Not hearing back from the very busy Damien, I thought I’d throw this out to the group. I honestly don’ think this is a problem with Audirvana per se, more likely a problem on my Mac Mini. Since we’re all running MACs, I thought maybe some of you have run into this weird problem or at least have heard of it. i’ve been tearing my hair out for weeks trying to figure out what’s going on - but I’m stumped.
Basically, whenever I import new files into the library, the new (and only the new) files are distorted for a few seconds at the beginning of the track. Dropouts, hiss, and pops for 2-3 seconds at the beginning of each new track. True for all file types, but I have mostly DSD64 and DSD128 files. This is happening across multiple DACs on this particular computer. This is a brand new Mac Mini with a 1GB Fusion Drive and 8GB memory. In fact, this is the 2nd new Mac Mini to have this issue. I had Apple swap out the first one. Here’s the exact model I have:
This problem doesn’t exist with Audirvana 3 playing the same files on two other MACs. These files play fine with AV3 on a Haswell i7 iMac with 16GB memory and 3TB Fusion Drive. Also fine with my MacBook with 8GB and 512GB SSD.
Typically, the distortion problem just goes away after a few days and I have no idea why. After several weeks of research and inquiries, I’ve concluded that it’s a not a problem with my DACs (4 total) connected to my iMac and MacBook. Everything is fine using those 4 DACs on the other two computers. That leaves the Mac Mini hardware itself or some configuration thing on the Mac Mini. Didn’t have the problem on my old Mac Mini which I upgraded to get a larger disk. I no longer have the old Mini but I’ll bet it would be fine playing these files if I were to revert back to it. The old Mini had run Audirvana for many years with no issues and it was updated to AV3 a few weeks before I decided to pop for the new one. The Mini is used solely as my music server. Very little other software is installed or running on it. The problem exists even with NO other software running on it.
This has been really frustrating. If any of this rings a bell with any of you, I’d love to hear your thoughts.
