Hi guys,
I know the subject is old but I just got my new Rpi2 yesterday and I’m facing the same problem and same symptoms as the first message of this thread( I’m using OSMC, up-to-date version)
However, I’m on a mac and on top that a Noob (I had never written any command until yesterday…). When I’m following eskildsf’s procedure about Pulseaudio, terminal says the following:
"Package alsa-utils is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Impossible de trouver le paquet pulseaudio
E: Package ‘alsa-utils’ has no installation candidate"
I’m kind of lost here and unfortunately eskildsf didn’t put any of the screenshot of his settings to get over this problem… Some help would be very appreciated 
Thank you very much!!
Ps:
- Sorry for my english, I’m french.
- My Dac is also a NAD D3020
