            Inconsistent Access to JavaSound SourceDataLine Through Minim
            Asked 2022-Mar-15 at 05:01

            I'm a not-so-knowledgeable person in the Linux world trying to understand an audio problem I have in a project. In short, I'm trying to get an audio output through a Java library called Minim (ddf.minim). I can get an output by listening to an input and enabling "monitoring." Monitoring echoes the input to an output. I cannot however get a working output line independent of this feature.

            Some context:

            This application is running on a BeagleBone Black with Debian Buster. This is an ARM microcontroller. My Java application starts up with the system as a systemd service as the root user. It runs in headless mode but with a virtual frame buffer (xvfb) because it's a Processing application. I have a USB hub connected to the BeagleBone, which hosts a USB-to-AUX adapter. The AUX side splits into the pink/green input/output cables. I have a mic connected to the pink end and earbuds into the green end.

            The problem:

            When Minim's getLineIn() is used to get an input, no errors are seen. Enabling monitoring doesn't generate errors either. Using getLineOut() will show errors that look like this:

            ...

            ANSWER

            Answered 2022-Mar-15 at 05:01

            I figured it out!

            Calling mixer.open() was causing problems. I guess Minim does this itself and expects users to leave it unopened when requesting a line.

            However, I did also have other discoveries.

            • Java and/or Minim are very sensitive to re-requesting audio resources, at least on Debian. Since requesting a line-in implicitly requested both an input and output for the monitoring feature, a subsequent call to getLineOut() would fail. You can, however, call Minim.stop() to start over and get resources again.
            • The AudioPlayer just seems broken. I can't get it to request a working output, but I found that FilePlayer works fine for some reason. You can even ask for an output with getLineOut() before making a FilePlayer. Maybe you have to call setOutputMixer() (without also calling getLineOut()) before getting an AudioPlayer in order for it to work.

            Convert Stack Exchange Markdown to Github Markdown
            Asked 2022-Feb-16 at 23:23

            Has anyone documented the differences between Stack Exchange Markup and Github Markup?

            I'm in the midst of a project to convert Stack Exchange Markdown to Github Markdown. It might be a little more complicated because Jekyll on Github Pages uses a Markdown derivative called "Kramdown".

            I've already written some of the conversion in my Python program. For example old SE posts with #Header must be converted to # Header.

            Another example are "> Block quote" lines have two spaces appended to the end of the line.

            Now it's starting to get tricky (for me at least) where in an image in SE is specified as:

            Converting thousands of Stack Exchange Q&A in markdown format isn't as easy as simply copying them over to GitHub Pages. The python program stack-to-blog.py was used to convert Stack Exchange posts to GitHub Pages Posts. The full stack-to-blog.py program can be accessed on the Pippim Website repo 🔗.

            The program automatically:

            • Creates Jekyll front matter on posts and front matter totals for site.
            • Selects Stack Exchange Posts based on meeting minimum criteria such as up-votes or accepted answer status.
            • If self-answered question, the answer is included and not the question.
            • If self-answered question, the accepted answer alone doesn't qualify. Votes from other are the qualifier.
            • Initial testing allows selecting small set of random record numbers to convert.
            • Converts Stack Exchange Markdown formats to GitHub Pages Kramdown Markdown format.
            • Creates hyperlinks to original Answer in Stack Exchange and Kramdown in GitHub Pages.
            • Creates search word to URL indices excluding 50% of words like "a", "the", etc. to save space.
            • Selectively inserts Table of Contents based on minimum criteria settings.
            • Selectively inserts Section Navigation Buttons for: Top (Top of Page), ToS (Top of Section), ToC (Table of Contents) and Skip (Skip section).
            • Selectively inserts "Copy Code Block to System Clipboard" button based on lines of code.
            • Creates HTML with "Top Ten Answers" with the most votes.
            • Creates powerful nested expandable/collapsible detail/summary HTML for many thousands of tags by post.
            • Remaps hyperlinks in Stack Exchange Posts to {{ site.title }} website posts if they were converted.
            • Fixes old broken #header Stack Exchange Markdown.
            • Converts < block quote Stack Exchange Markdown into what works in Jekyll Kramdown.
            • Convert Stack Exchange tags to fenced code block language.
            • When no fenced code block language is provided, uses shebang language first (if available).
            • Converts older four-space indented code blocks to fenced code blocks.
            • Converts Stack Exchange Hyperlinks where the website post title is implied and not explicit.
            • Prints list of self-answered questions that were not accepted after the mandatory two day wait period.
            • Prints list of Rouge Syntax Highlighting languages not supported in fenced code blocks.
            • Prints summary totals when finished.

            State T is not terminated, it is "stopped by job control signal" (man top).

            To get the processes into this state, you probably sent SIGSTOP to them (kill -STOP ...). Instead, you should have sent a SIGTERM (the default), and you can still do that now. If that doesn't work then send a SIGKILL.

            SDL_memcpy is memcpy, meaning first argument is destination, and second argument is source. In both ouf your callbacks that order is wrong, your input callback just erases your stream data with what is initially stored in buffer (zeroes), and output callback don't output anything but instead copies garbage to buffer.

            Similarly your if (out_pos >= in_pos) branch should erase stream, not buffer.

            Note that your requested audio format is F32 (not guaranteed as you allow format changes), but your debug printfs interpret it as uint8. That will not affect audio playback, only how relevant output is.

            how to make firefox use alsa audio output (pipewire)
            Asked 2021-Oct-10 at 18:55

            I am having sound issues with my firefox. The problem is that, sound comes off as almost muted and sounds like it is coming out from the back speakers. My firefox is using wayland

            I've had a similar problem with VLC. I was able to easily fix VLC by setting the audio output module from pulseaudio audio output to ALSA audio output and selecting Default ALSA Output (currently PipeWire Media Server) as the Device. like shown here.

            Firefox about:support shows the following for the audio output

            when I was installing arch, I installed the following: alsa-utils, pipewire, pipewire-alsa, pipewire-pulse, pipewire-jack

            my pavucontrol is configured like this. If I select Analog Stero Duplex as the profile, then audio from all sources through firefox works . The only problem is, I can't adjust the volume anymore. The sound is either 0% muted or 100% all the time. With Pro Audio, I can adjust volume but some sounds will not work in firefox.

            I was able to partially fix the sound issues on firefox by installing xdg-desktop-portal-gtk. No most youtube videos thru firefox works great. Not all of them work. Some videos still have the same sound issues. I don't know why. For example, this video https://www.youtube.com/watch?v=2iarxxm-v9w Other non-youtube sounds still come off as muted. For example, sounds from this website: https://erogol.github.io/ddc-samples/

            If there is a way to configure the alsa/pipewire settings globally, so all applications use it as default, that would be ideal. But getting sound to work on firefox just itself will still be a big win for me either way.

            You can not create an instance of SinkInputInfo. You can also not store instances of it anywhere.

            The reason is that it is intended to be only valid inside the callbacks:

            https://www.freedesktop.org/software/pulseaudio/doxygen/introspect.html#query_sec

            Data members in the information structures are only valid during the duration of the callback. If they are required after the callback is finished, a deep copy of the information structure must be performed.

            libpulse does not provide any means to copy or free the SinkInputInfo pointer type.

            You can however use anything inside the struct:
