I have now been able to do a head-to-head comparison of the BBB running volumio 1.4 and the R-pi-B and R-pi=B+ running v. 1.4 and 1.4.1 respectively, and I wondered if anyone had experienced the same issues I had.
– Using a DragonFly DAC then (this is std. I think, but ought to be highlighted for others perhaps):
(i) It must be explicitly unmuted by using sudo alsamixer
– NFS mount over gigabit ethernet.
The real problem is that no matter how much buffer time I give the system, or how much read/write size I give to the NFS mount,
I experience (digital) pops and clicks. They are much more frequent with 24/96Khz material, but are present even @ 44.1kHz.
In contrast, with Rune audio with the same hardware setup, I experience no such sonic problems.
Any suggestions as to how to fix this under volumio?
