Dear current-users, When recording with a recently updated kernel, I experienced some kernel panics. I think this has been the case for some time now - but I only got around to reporting the panics now (apologies). I captured two panics in my dmesg, I guess the second is most relevant.
I have also managed to record audio using ffmeg4 without a panic, but the audio plays back too slow and is a bit garbled (I was unable to diagnose the quality problems - but the sampling speed was much higher than specified). Any tips would be appreciated. uname: NetBSD HOME 9.99.17 NetBSD 9.99.17 (YORICK.amd64) #1: Sat Oct 26 00:06:47 SAST 2019 root@HOME:/root/build.amd64.local/obj/sys/arch/amd64/compile/YORICK.amd64 amd64 dmesg: ...
