I think the dac / amp is not being recognised correctly. Maybe it is expecting an on-the go device to be plugged in and not a raspberry pi. It says in the blurb that one can connect a smart phone by the usb (which is a different connector than normal for a dac) so maybe it is a "smart" connector. Have you tried using a phone ? I don't really understand dmesg very much (I'm trying to learn) But yours goes like this > > > [ 5.389126] zram: Added device: zram0 > [ 5.405537] zram0: detected capacity change from 0 to 244580352 > [ 5.415881] random: mkswap: uninitialized urandom read (16 bytes > read) > [ 5.489085] Adding 238844k swap on /dev/zram0.
