No sound

I have Raspberry Pi and HiFiBerry DAC+ standard. I have installed latest version of Volumio as instructed and I do not get any sound. I have tested with test program and DAC is working OK. During boot I get following error message:

transientlog: Premission denied
Error openning ‘/dev/input/event*’: No such file or directory

And few lines below I get:

startpar: service(s) returned failure: transientlog …cat: /run/ No such file or directory

How can I fix this problem?
