Hi,
I was wondering if there are other people that have a similar problem with the Topping E50 under Linux (Pop OS/Ubuntu 22.04 and in all honesty it doesn't seem to be limited to the E50)
whenever I Play some music or watch netflix in the browser there is a slight crackle that seems like it has something to do with resampling or buffering.
In order to rule out any hardware problems. I tested the E50 on the same machine with Windows 10 (changed the nvme drive and installed windows 10) and the sound was fine (no crackle)
I switched back to Linux and tested another DAC (Matrix X-Sabre Pro) and that had the exact same problem as the Topping E50.
I also tested audio with a Jabra wireless headset I have attached and there is no sign of any crackle there.
I've used the guide on:
forum.manjaro.org
And tested the suggested settings in order to see if that would change anything but it didn't seem to help
Note that alsa-monitoring.conf is in 50-alsa-config.lua in my caser since I use Wireplumber (well the distribution does)

},
},
In pipewire.conf:
default.clock.rate = 48000
default.clock.allowed-rates = [ 48000 88200 96000 176400 192000 352800 384000 ]
default.clock.min-quantum = 1024
In pipewire-pulse.conf:
pulse.min.req = 1024/48000
pulse.min.quantum = 1024/48000
Does this sound familiar for someone? and if so any suggested fixes (besides switching back to Windows
)?
Thanks!
