I'm also experiencing the occasional clicks and pops since I switched from a Cambridge CXA81 DAC to an Amanero based DAC. With the CXA81 I have never experienced any clicks and pops. Running the Allo version of DietPi (v7.0.2). I ran the command to check the driver version. version: v2.0.0 srcversion: 54F748FF414BD3C621436B9 vermagic: 5.10.17-v7 SMP mod_unload modversions ARMv7 p2v8 This looks like the correct driver to me, so are the any other suggestion to fix the problem?
