I'd like you to test with backport drivers as well: > https://github.com/takaswie/snd-firewire-improve I tested this DKMS version, it's easier for me and with less impacts. What I can say is that my unit is running now normaly on my computer, with $ uname -a Linux deiphobe 5.3.0-20-lowlatency #21-Ubuntu SMP PREEMPT Wed Oct 23 17:03:51 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux kernel, on Ubuntu 19.10 Running the simple DKMS install version on the README of the snd- firewire-improve, with a recent git clone Tell me if you need more information so far. I continue on testing things, but for the moment, 0 problems (I also have a audio unit on USB (GTX headset on USB) for audioconferencing stuff (Zoom) and so far, no problem at all, I can use both. Same with the NVDIA output over HDMI, on my screen (with a crappy small stereo inside the screen). Very cool to have the ADAM F7 monitors sound back!!!!!! **thanks**** !! > > > > Regards > > Takashi Sakamoto > _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
