[Linux] My two identical micros are not detected

SilverYoCha commented 3 years ago

I have two identical micros, those provided with Let's Sing. They seem to be logitech ones, on USB : (alsamixer) My system is recognizing them : (pavucontrol) When I speak in front of my micros, I see the according level bar working.

Actual behaviour

But when I start ultrastardlx, the microphones are not detected. I can choose between and

When ultrastardlx is running, pavucontrol is displaying that: And the according menu looks like that:

During my lot of tries before posting an issue, I already succeed to see them into ultrastardlx, but it was not working well. Application took time to switch between the first micro to the second one into options. The application was generally very slow.

Expected behaviour

The mircos should have been provided into the sound card selection. (Ultrastardlx is working fine under Windows system with my micros)

Steps to reproduce

I hope someone could plug same kind of micro than mines to reproduce...

You use PulseAudio with the default configuration. PulseAudio grabs all real ALSA devices and installs a single virtual ALSA device called "pulse" that is routed to the default audio device. If you want to expose multiple microphone devices as ALSA devices, you need to configure multiple instances of the pulse ALSA plugin. See https://wiki.archlinux.org/title/PulseAudio#Expose_PulseAudio_sources,_sinks_and_mixers_to_ALSA

Or you disable PulseAudio while playing ultrastardx with pasuspender to give ultrastardx direct access to the microphones.

Or you build ultrastardx --without-portaudio so that SDL is used to interface to PulseAudio without going through the pulse ALSA plugin.

Thank you very much for your help @s09bQ5. I finally chosen your third solution. After that, my microphone are well detected and selectable into options. But I have some huge slowdowns when my USB microphones are set. From microphones options, when selecting an USB one, the software takes 2 or 3 seconds to switch over. During a play, the software does not respond fastly to the keyboard and I am almost obliged to kill the soft from command lines. I thought that my PC has USB problems at first. But after trying other programs using microphones, I discovered that they were entirely functionnal. I don't know what it is going on. Some logs: Error.log
