And which can be circumvented by starting the applicatino image with the --no-sandbox flag by the way. But back to using jack for alsa-only applications. Following the guide on https://jackaudio.org/faq/routing_alsa.html I installed the libasound2-plugins Debian package, which includes the jack pcm plugin for alsa. This plugin is activated by /usr/share/alsa/alsa.conf.d/50-jack.conf as a hardware plugin without conversions, meaning that it is tied to jack's sample rate and bit resolution. I was able to create a "plug" device which takes care of this conversion in an ~/.asoundrc yielding pcm.jackconv{ type plug slave { pcm "jack" } hint {description "jack plugin with software conversions" } aplay -L then lists this device. My next question is, how can I tell applications to use this device? I want to avoid declaring it the default in .asoundrc with an pcm.!default{ type plug slave { pcm "jack" } hint {description "default jack plugin with software conversions" } I found out that there is an environment variable ALSA_PCM_CARD= but this can only set hardware devices but not pcm device names such as my jackconv. Then I discovered ALSA_PCM_DEVICE and tried to start jitsi with ALSA_PCM_DEVICE=jackconv ~/bin/jitsi-meet-2.0.0-x86_64.AppImage but no device "jackconv" shows up in jitsi nor are any jack ports created for it. Is there something I am doing wrong? Thanks for all ideas! cheers, P _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
