are you using RedOS or other OS? for RedOS try the link and use the older 2G version, it can do the first unfold of MQA. Holo Red Red-OS-20221228-2G image https://magnahifi.com/holo-audio-product-downloads/

the problem with CM4, there is no OS support Tidal connect, I used to use CM4 with volumio, PiCorePlayer, as Roon endpoint etc. and upgraded to Red, and it sounds better and easier to manage, you can just enjoy the music....

try the 20221228-2G, should work for you, it supports roon and is also able to decode MQA. mine with newer SN, both images work for me.

one of their older red OS can decode mqa, the newer one is upgradable to the current latest OS. Does anyone hear any difference in SQ for these 2 OS?

Does anyone use Tidal with Red? and noticed there is one older Red OS able to decode MQA, which all later versions are unable to do it? is MQA decode be back later on? Does anyone know where is their official website for firmware and OS? This is the only problem I have with Holo, they don't...
