Hi Volumio community,
I am calling the group intelligence to help me unlock an feature of interest for people bridging old school analog with modern digital feature.
Having the opportunity to play vinyls trough Volumio would be very appealing to benefit from source selection and the DSP features allowing speaker/room correction.
I know this is achievable using the Hifiberry DAC+ADC hat, but it is also currently the only possibility. So if you want to use a more qualitative DAC hat (Audiophonics or IanCanada), you are stuck in a dead end.
Recently, a very tenacious chap unlocked the use of ADC card (master mode) on raspberry Pi running Raspian and tweaking some scripts (see here). It is recognized by ALSA as a recording device and used to save vinyls in digital format.
I could successfully reproduce the procedure on the Raspi OS, and got it to compile on Volumio OS by loading first the kernel sources (shell command : volumio kernelsource) followed by the procedure detailed for Pi OS.
Unfortunately in Volumio OS, the compiled driver does not seem to be loaded in ALSA as the arecord -L output stays empty.
So I wonder if there are some Volumio ALSA masters around that could give a hand here to unlock the last bit of the process? I am wondering if there is some ALSA environment tweak in the Volumio distro that prevent the driver to be mounted.
Thanks a lot to anyone who could provide some insight/help.
