Is perfect playback of 44.1khz FLACs streaming from a NAS on a Pi 3 an unrealistic proposition?
A few months ago I switched over from Rune Audio, installing Volumio on an Intel NUC I had lying around. This worked brilliantly but I feel like using an NUC just for audio playback is overkill so I’ve switched to a Pi 3 running Volumio. My setup is: WD MyCloud-> WiFi -> Pi 3 -> Denon DA-300USB USB DAC.
However, I’m just a little disappointed by the playback. It’s quite close to being fine, but I get one or two glitches at the start of most songs and usually one or two more in the middle of each song.
I know the Pi USB and WiFi share the same bus (or something like that, I’m no hardware expert). Does this mean that I’m asking for too much from the hardware? Or can I optimise the playback in the software? I’ve tried increasing the buffer size without much luck.
Failing this, can anyone offer any alternative hardware suggestions? I’d be willing to spend another £100 or so to get perfect playback.
I think my current options are:
- Try a Pi 2 with a USB wifi dongle (not sure if this would be an improvement).
- Ditch the USB DAC and try something like the Hifi Berry DAC
- Reluctantly return the the NUC, which I really want to use as a media centre.
- Investigate other Pi-like computers - any suggestions?
Thanks for your help!
