im absolutely stuck on getting

Ubuntu Studio 20.04 + Ardour 5 + EMU 0404 PCI

working as it should.

I did install Ubuntu Studio on an old PC of a buddy of mine. He wants to do some recordings and it is perfect to "recycle" the old machine. This PC includes a EMU 0404 PCI.

I already googled many sites and did many things

  • re-installed ardour & ubuntu studio controls
  • re-installed jack
  • tried to install driver/firmware for emu0404

What is working:

  • Playing recorded stuff --> Output to stereo-out works
  • Jack seems to work
  • Running a Behringer U-Phoria UM2 (USB) Device worket --> Playback AND Recording --> But this device should not be used --> EMU 0404 already included in the PC

What is not working:

(This is the reason im posting this)

  • I can not use the EMU0404 stereo-input to record stuff --> No matter what connections in ardour i make or what additional devices i add in the ubuntu studio controls --> I never got it working, that the (directly into the stereo input) plugged in guitar gets routet to the input of ardour

Due to the fact that everything is there and and works, i think that i dont understand all the dependencies in the whole system (Ubuntu Studio Conrols / Qjackctl / Pulse Audio / Ardour Channels/Buses/Hardware/Setting)

I have no clue what to try next, this is the reason why im asking for help of you guys. But im annoyed that im near the finish and only the very last thing ("Getting the input-signal working") is not working.

Below im trying to post as much information as possible, so maybe one of you can tell me what i am doing wrong!

Thanks a lot in advance!

Already tried this to re-install alsa firmware:

cd ~
wget ftp://ftp.alsa-project.org/pub/firmware/alsa-firmware-1.0.28.tar.bz2
tar xjf alsa-firmware-1.0.28.tar.bz2
cd alsa-firmware-1.0.28
./configure --enable-buildfw
cd emu/
sudo make install

And here as many screenshots as possible:

At the moment i completely lost the overview what do connect or activate







qas mixer


  • The screenshot of qasmixer shows only output devices, but we need to see capture devices. Also scroll down with the small scrollbar beside the two buttons in the lower right corner to see more options, best to make the window bigger so all options fit in the window. – mook765 Dec 6 '20 at 14:37
  • Hello mook765, thanks a lot! I dont know how to switch to "capture" devices ... this is all i can see here: dropbox.com/s/2nti282bv7vh5lt/… – SHUred Dec 6 '20 at 16:18
  • You can switch displaying playback and capture devices on and off with te two buttons in the right lower corner. – mook765 Dec 6 '20 at 16:22
  • Aaaah! Now i get it! Seems like some of the inputs are deactivated hah? Is the "stereo in" something like "aux"??? dropbox.com/s/lbs0p4p1pte183a/… – SHUred Dec 6 '20 at 16:29
  • It's hard to see due to dark theme. You'll have to try out a bit. I use only built-in audio which has totally different options. Also check the connections inside jack with carla, maybe this gives a clue. – mook765 Dec 6 '20 at 17:39
