Audio stopped working on Linux Mint 22

[defensem3ch]

It seems that I am not able to hear any audio output from the kit editor, possibly due to the patcher selecting an incorrect default audio output? I am still testing pipewire audio setup in Linux Mint, but it might be nice to consider if there is an easy way to select an audio device, possibly via commandline argument.

Hmm isn’t that functionality supposed to be built into the operating system itself?

…by that i mean… if i have windows running, i can click a speaker icon and select the output… Is it different in Linux?

Yes, but the java app seems perhaps to ignore the default audio device. I've spent some time researching the issue but unfortunately haven't stumbled upon anything helpful yet.

Not sure if this is related, but wav files exported from Reaper only play the first 1 second in kit manager, but the whole loop is actually saved to the kit.

Other wav files seem fine, not quite sure what the difference would be.

[jkotlinski]

That seems weird. Could you attach such a wav file here to this issue and I can have a look?

I think I just figured it out. It's ok if exported as 16bit PCM wav, it's 24bit PCM wavs that it just plays first second.

So there is as solution, probably not a priority to fix, if a fix is even needed.

Links to download the 2 wavs: 24 bit: https://i.damselflycreative.com/media/16bit.wav 16 bit: https://i.damselflycreative.com/media/24bit.wav

I tried adding the 24-bit sample and it worked just fine on my computer. But it relies on native Java function AudioSystem.getAudioInputStream to do the conversion. Maybe it is buggy on Linux and needs to be replaced with bespoke code that actually works.

[jhob101]

Good to know. 16 bit is fine anyway, not like you need especially high quality source audio!

I'm using pipewire, so might be something related to that.

I was able to replace some of the code in Sound.java to use the "pulse" audio device and this is working for me. In the future it would be more ideal to implement this as a menu item, I may work on this and provide a pull request if I ever have enough free time.

// Get the specific mixer (audio device) containing "M4" in its name
        Mixer mixer = getMixerByName("pulse");
        if (mixer == null) {
            throw new LineUnavailableException("No audio device found containing 'pulse' in its name.");
        }

        // Get the Clip from the selected mixer
        Clip clip = (Clip) mixer.getLine(new DataLine.Info(Clip.class, new AudioFormat(PLAYBACK_RATE, 16, 1, true, false)));
