A little explanation
due to some structural changes required by the new Raspberry Pi kernel, on Volumio3 a new parameter has been implemented on every entry on the dacs.json file (alsacard)
if the new parameter is empty, the corresponding DAC will not be shown on the dropdown list of available DACs. This is the case of TAUDAC.
most of the I2S DACs have been filled with this additional parameter, with help from the community. For some of them this wasn’t possible, because the team doesn’t have all the DACs, and no entry was provided by the community.
If you can help to provide the required parameter, I can create the pull-request for adding the alsacard entry for TAUDAC.
- connect the SD-card to the PC
- open the file “userconfig.txt” with Notepad++ (under Windows) or with any text editor (under macOS or Linux)
- add the string “dtoverlay=taudac” on a new line and save
- insert the card on the Raspberry Pi, power it up and then follow the instructions from the initial post of this thread
