Re: sndio: troubleshooting no input
No, it was set to 0. I set it to 1 and that fixed the issue.
Thanks!
Also, Maurice mentioned "sndioctl -d" so here is the output:
073:input[0].level=0..255 (120)074:input[1].level=0..255
(120)105:input[0].mute=0..1 (0)106:input[1].mute=0..1

Re: sndio: troubleshooting no input
Do you have sysctl kern.audio.record=1 ?

Re: sndio: troubleshooting no input
sndioctl -d Have a look at man sndioctl Good Luck
sndio: troubleshooting no input
Hello,
I have an amd64 laptop with OpenBSD 6.7 and I am only getting
zero-valued samples when recording. Is there any checklist I can
go through to ensure nothing is muted and that I am reading from
the correct input device?
I have tried both aucat and a C program I wrote (attached).
Thanks,
Aaron Miller
