Hello ! Thank you all for reading, and for your feedback ! I feel less alone. So : - No sound from the motherboard's chipset. It's a long time i have kill it in the bios - i think 10 minutes after buying the motherboard. - No wifi chipset, or wifi usb dongle, or app using wifi on my computer. - My Windows Manager is I3 - very simple, i like it. No fancy stuff. 0 GVFS items packages installed. - Yes i try to remove all services that seems 'suspect' but so far...a systemctl list-units gave me only the vital (log/mount/swap/networking service) The only suspect i don't know what to do about are : apt-daily.timer loaded active waiting Daily apt download activities and remote-fs.target loaded active active Remote File Systems Not sure they are vital. But i see nothing about them on the journalctl that matches the time of the XRUN - the apt-daily time occurs like 1 time every 8 hours or so. The Card(s) are alone on they interrupt line - already manage that - thank linux audio wiki & others, well explained and documented, and still up to date. Thank you again for reading you all ! Appreciate that a lot ! ps : I think it was a wrong routed message from David. J but i do not want a RT Kernel (do i really need one ?!) for my simple recording needs. A good low latency, well configured Kernel should do the trick. pps : I do not receive the list on my Claw-Mail client anymore (few days maybe) is the bot out ? Or it's only me ? I've been banned !? :) _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
