Audio tracks without function on Ubuntu-20.04?
Posted: Tue May 19, 2020 11:21 am
Issue#1: MusE-3.1 build from GIT refuses to create audio parts on an audio track. There is no way to create a part; neither using the menue entries nor the double click between locators.
Issue#2: A created input track if set to stereo and connected to the jack input (stereo too) only receives signal on the left channel, according to the level meters. This mono sicgnal cannot be recoreded because of issue#1.
I tested this with audacity (audio mode: jack, stereo track) and it works.
Observation: MusE reports on startup that it cannot read the jack version from its API.
Version conflict on 20.04? MusE not adapted to recent JACK API changes?
An here is my yes-list:
- Yes, I connectet both inputs to the audio track. Everything looks perfect!
- Yes, I removed *all* configuration files (MusE, jack, qjackctl) many times to start over from scratch and I do not have a specific ALSA config file.
- Yes, I rebooted.
- Yes, there is no pulseaudio trashing the audio system. Uninstalled!
- Yes, there is no other app running which would do audio.
- Yes, I tested jackd started by MusE and jackd started by qjackctl, with many many different options.
MusE audio is totally screwed up on my PC with no ideas left how to fix this. I spent 3 hours. Ideas, anybody?
