hello, i am new user of ALLO usbridge signature player but so far not going well…
I try to stream from my Synology NAS 220j. I mounted directory as NFS. I see it and sometimes i can play music from it… But i get this error almost all the time
“Error Failed to open “alsa” [alsa]; Error opening ALSA device “hw:5,0”; snd_pcm_hw_params() failed: Input/output error”

It sometimes is gone after reboot but after playing with playlist i get it in minute…
i get VOLUMIO preinstalled on card, power supply is 3A dual Shanti… I don’t know what can be wrong ? i try to look on net but so far no right answer what to do.

thx for help in advance
