I have just installed volumio on my Pi however when i play a track from my nas i get a lot of audio drop outs. this is through the usb dac or the analogue out
i have tried wired and wifi network conection
can anyone advise what i can do to resolve it.
The thing is there is an issue with USB audio on Raspberry Pi (that would explain the reason why you are having problem with your DAC but not necessarely why you encounter the same with the Analog out).
I just set up Volumio 1.5 on my Cubox 2i, connected to a NAD D3020 amp with built-in amp.
It’s a sweet setup, and I got it working well for the most part, but I am still experiencing occasional pops and hicks when streaming over AirPlay. Modifying the shairport start-cmd line in the PHP config helped, but its still not entirely gone.
I see you RPIers updated the rpi software (rpi-update) and things were better. I do not have that alternative. Anybody have a clue what libs/software is included in that update that may have helped this?
This is what I did. Not all of it may be necessary depending on your situation. I have multiple video streams, VOIP, mega pixel security cams and home automation running on this network.
Router CPU no more than 5%, memory at less than 20% - Model CCR1009
no spanning tree (RSTP) on LAN bridge. Cannot run SONOS if this is turned off. Turning RSTP off leaves you open to network loops.
DHCP authoritative for fast dhcp resolution
Gigabit ports with LAN interfaces sharing a dedicated switch chip when bridged. I plan on moving to a gigabit managed switch to offload resources even more on the router. Switch would connect via SFP to the router.
bonded dual gigabit links to Synology NAS
DNS cached
Local time server so that only one host on the LAN interfaced to the internet time servers
disabled unnecessary services on the router
Tuned wireless radio links to between 55-70dbm between stations and Access Points(AP). Too strong a signal led to lower throughput/dropouts.
Wireless bridging between AP and station serving RPI using TDMA (NV2 in Mikrotik terminology) protocol to reduce latency. RPI cabled directly to station. No wireless adapter on RPI
I miss the days when I could get great sound just by lowering the tone arm on my vinyl . I hated getting up every 15-20 mins to turn the record side over though.
I switched from wired to wireless, no change.
Again; playing files from NAS (320kbps MP3s) via Volumio Web UI has no issues.
The slight cracks and pops come when playing over AirPlay.
Changing shairport startup command made things quite a bit better, but its still not perfect…
