A.)
First try with HiFiBerry DAC plus because of my special interest to make the HAT working. The positiv was: Interface was asking for reboot after selecting the DAC. But: there was no clear indication that reboot was carried out. Finally the good news for me: HiFiBerry DAC plus is working attached to TB with this Beta.
B.)
Quick try to connect HDMI. After reboot TB shows the following on the screen:
Also the Web interface was not accessible - just a waiting cycle. So I gave up.
C.)
Reconfiguring to SPDIF. I must say without have the possibility to do a A/B comparison my favoured testing tracks have more punch, more transparent and clearer bass - wow!
The only drawback is 88,2 kHz and muliplier 176,4 kHz gives a noisy, crapy sound over the music. Connect to older equipment also 88,2 capable gave silence only. All other sampling rates up to 192 kHz are working fine. BTW: volumio 2 has no such problem.
Further investigation showed: this is true for Hires sources (Qobuz) as well as for selecting the appropriate upsampling rate in the setup.
Runnig a log while starting a 88,2 hHz tracks gave only this significant difference (left volumio 2 - right volumio 3):
Let me know if I can perform further testing on the OS side.
