Audio on LinuxLee Hawthorn January 16, 2022 #Linux #Audio
After I upgraded to Win 11 I managed to get two interfaces working with ASIO drivers (from different manufacturers) with separate input/output in my DAW. Note, I did end up replacing one of my interfaces with an analogue desktop mixer/interface. With hindsight, I should have bought a mixer at the start =-)
Thankfully the market for audio bits and bobs is strong.
Win 11 even notified me after an update that the source audio has changed. What a difference that makes.
I did have to learn a bit more about mixing concepts like PFL but it wasn't too tricky. Oh I had to get a DI box too along with XLR cables but this gives flexibility for silent practice with backing tracks on youtube/spotify with guitar/amp/mic
I use Windows and Linux for Audio recording/development. I have to use Linux when I want to use multiple active interfaces as Windows doesn't provide that functionality. Furthermore, I have a USB mic and instrument which means I have 2 interfaces. Windows is very good for audio these days with 1 interface. I can get really low latency.
When I started to use Linux/Ubuntu I found it tricky to get a good base sound.
This post goes into a bit of detail of how to do that. I'm using my sound card as an example. By default, this sound card was muted.
Control+ALT+T to open a terminal.
Into this terminal enter
You can see my default soundcard is from my GPU. Press
F6 and select the sound source you want to change. I needed to select HDA Creative
Now this sound was muted, so I had to increase the
PCM level. It was 0 for me. I also had to mute
<Enable 0> as the sound was very tinny.
We can mute channels by pressing
m - they will show
MM when muted or
00 when unmuted.
I lost these parameters when Ubuntu was rebooted, so I needed to save the parameters and reinvoke them at start up.
Close Alsamixer and in the existing terminal enter =
alsactl --file ~/.config/asound.state store
Paste in the code below
[Desktop Entry] Type=Application Terminal=false Name=alsarestore Exec=alsactl --file ~/.config/asound.state restore
I use Pulse Effects to apply effects to music.
sudo apt update sudo apt install pulseeffects
We can create and use presets with Pulse Effects. I installed presets from this GitHub repo
I had to use the manual installation from the Pulse Effect branch.
This gives me good audio to start with. You'll be able to use some of these techniques to get a good sound on Linux.
I wish Windows was able to manage multiple active interfaces (eg USB Mic+Interface). I have had mixed success with ASIO4ALL. MacOS and Linux has it.
There is a new multimedia driver under development for Linux called pipe-wire. This will make using multiple interfaces even easier. Hopefully Ubuntu will have this set up in the next version. I understand Fedora already has pipe-wire set up.
