I found out Pulseaudio was holding "native" driver and when I stopped
and got access to Audio,0 - things were more expected. AFAIK -
underlying chip is a 5102 also. Interesting this time sample size format
S24_3LE.
Repeat of 1st test - squeezelite opens at 44.1Khz (default value) but
when I play a 48Khz - it reopens at 48Khz.

Get logs working or you'll never be certain what's is going on.
What OS are you using ? PCP, Ubuntu, raspbian, ???
