That mic gain is set to 0:0 makes no difference really bothers me. Not sure exactly what "monitor" is, but it seems to not work. I guess I need to read a bunch of documentation on snd_hda and sound. Oh, I did remove the mic items from boot/loader.conf and rebooted, but it made no difference.Also tried ALSA without luck,either. Tobias, I'm averse to trying ffmpeg, but I really want to only record the video window and not the entire screen and I don't know of a way to do this with ffmpeg. -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683 On Fri, Apr 3, 2020 at 6:55 PM Kevin Oberman wrote: > On Fri, Apr 3, 2020 at 1:15 PM Hans Petter Selasky > wrote: > >> On 2020-04-03 19:29, Kevin Oberman wrote: >> > I am attempting to capture screen video with >> > multimedia/simplescreenrecorder and can't seem to record the audio. >> Video >> > is fine, but the audio silent.
