My USB Dac came by mail recently, a HifiMeDiy Sabre USB DAC (96khz/24bit
- ES9023+TE7022)
It seems to work fine on my machine. Quite compact, too.
I encountered one issue: the DAC does not handle 88.2kHz music. 44.1 ok,
96 ok, but they left 88.2 aside.
When I play an 88.2 record, squeezelite logs an error and goes silent.
In fact, it remains silent until I kill and restart it. Power on/off is
not enough.
For the moment my solution is to sync with an SB3 ;)
Does something else make sense ?
