New comment by biopsin on void-packages repository https://github.com/void-linux/void-packages/pull/31286#issuecomment-879761647 Comment: Also I'm experiencing more and frequent underruns in Reaper with this 1.2.5.1. Downgraded again and ~~issue solved.~~ Edit: well not quite, the underruns count is much more present now then before, might be tied to kernel updates.. Edit2: currently building 5.4.132, as there are some alsa:usb-audio fixes.. Edit3: unable to track this down, my only assumtion is fixes in ext4, as I mostly diskstream from a sata3 10,000 RPM disk. Temporary solution changing buffersize from 128ms to 512ms which is utterly crap for recording, and I will look somewhere else for help.. Im fine for merge.
