Package: pipewire Version: 0.3.38-2 Severity: normal Dear Maintainer,
I'm aware of a new release (0.3.39), but since there no pipewire-media-session for that new version, I couldn't get rid of the broken package warnings on aptitude. I have an external firewire interface (M-Audio 410) and when I try to record my guitar from it on Ardour the sound is very weird like if some tremolo effect is applied on the source. A microfone connected to the onboard sound card is recorded as good as it can be, just with the usual annoying noise. The Click sound from Ardour is perfect. The sound also has the problem even if I just set Ardour to throw the sound to the output (same effect if the output is HDMI from the screen or the output of the onboard sound card). The curious thing is that when I connect the capture channel directly to the output (or passing throught guitarix or rackarrak) the sound is perfect. It doesn't matter if I have PipeWire running with Pulseaudio (as described in Debian wiki, with the linked libraries) or by itself (uninstalling Pulseaudio and rebooting). I manage the input and output connections with qjackctl. At this point one might think that this is something related to Ardour, but the same occurs when I use OBS Studio, with some audio file in a scene: I have to set the monitor of this input to Off in Advanced Audio Settings (so I don't hear the audio in that scene). It seems that this artifact appears on sound when the signal passes through some software (like Ardour or OBS) towards the realworld output (HDMI screen or onboard speaker output), whatever it comes from (a file or the firewire interface). It seems ok when passes through some other software (rakarrak and guitarix), whenever the source is the same filed used in OBS, played by mplayer to guitarix to speakers connected on the HDMI screen, or the sound captured by the firewire interface. I also tried audacity, but couldn't manage to make it capture sound from the interface, just from the microphone connected to the onboard soundcard. It does not in the graph connection of qjackctl. Sorry for the long message, but I tried to describe the situation here in full detail (as much as I could). Of course I can run any tests and provide information (hardware and config details) that may help to fix this. Thanks in advance.
