DAC problems

primy22

I have question about the proper setting for the DAC input output.
I have connected Volumio to the USB port of BTA30.
Volumio recognise it and even on the BTA30 i get the white led which means there is signal on it.
BUT nothing is comming out to amplifier. i get nothing out of any port (optical,coax,analog).
On all ports silence altough aplifier priperly selects the input mode.
In BT TX configuration works: Volumio > BTA30 > BT Earphones. OK
Also BT RX configuration works: BT Phone > BTA30 > Amplifier(SPDIF) OK

Volumio > BTA30 > Amplifier .... NOT OK
What am i doing wrong.

Thanks

Let me confirm again with your connection:

Volumino-usb-bta30-coaxial-amplifier, no sound?

Have you switched the bta30 to default output in the volumino?

Volumio-usb-bta30-optical/coaxial/analog-amplifier, no sound I tried them all.

Yes, BTA30 is the default output on Volumio.

in addition, Volumio-usb-BTA30 bluetooth TX-Earphones works.
Which means that the data from Volumio definitely works.
I just have a problem to anchor USB data over DAC to amplifier.

Dear friend,

The engineer told me that it may be a compatibility with your Linux system device.

This is a method mentioned by other user, you could check whether it may help:

But to do that, I need to edit the daemon.conf file.
It seems the default sample rate used isn't handled really well when
USB output is used.

The problem is that this editing of .conf file forces the output in
48khz or 96khz.

understand,
Volumio has the option for resampling but it only works for internal data like web radio and music from  storage. Unfortunately you cannot resample airplay data. Also I didn't manage to successfully edit daemon.conf.

1. will there be a FW upgrade or this is a HW limitation?
2. Just to verify.... if I use optical or coax input on BTA 30 I will not have this problems?

Thanks

1. For the compatibility issue, we could not tell whether it could be solved via firmware update currently.

2. Yes, if you are using optical or coaxial input, there will not be this problem.

Yes, you could adjust the volume of the software for playing the music files for help still.
