No, ALSA/Troubleshooting doesn’t help either. No, PulseAudio/Troubleshooting doesn’t help. But things evolved, and the kernel in Debian testing evolved: 5.9.0, 5.9.6, 5.10.0, 5.10.19… and the workaround stopped working completely and forever! I also regularly tried the similar Debian testing weekly live images (mostly the KDE one), and I noticed that starting with the one from, it needed one or another of the classical fixes based on adding a line options snd-hda-intel (with further options) to nf (there were several options that worked for my hardware… when they worked).Īt first, I thought this means the next Debian 11 Bullseye, once released as stable, would support this bloody Realtek Intel HDA, even if it requires a small workaround–in contrast to Ubuntu 20.10, which refused to react positively to any attempt to make the headphones being detected. Debian 10.9 still works perfectly out of the box. Debian Buster works just fine on my hardware out-of-the-box for a LiveCD (on a USB key, using Ventoy) the current stable “non-free” edition, with extra firmware, preferably KDE (but MATE is fine too). Since pavucontrol is two clicks away from the volume control applet in XFCE, this is what I’m going to use when the headphones don’t get recognized. You know, even when the jack is not recognized, pavucontrol (PulseAudio Volume Control) can switch the output to it if wanted so: Switching the audio output should have been the default behavior, with a possible software command to revert it, but it’s not how those retards have designed the hardware. With the modern non-switching audio jacks, the hardware (here, Realtek’s ALC282 chip) knows when a jack is inserted (impedance, duh), but instead of automatically switching the audio output, it waits for a command given by the OS via a driver. This is why I could read on some web pages about the “audio jack driver” no, the driver is not for the jack itself. In this case, they uninvented the audio jack that automatically and mechanically switched the audio output upon the insertion of the jack: Of course, the funny thing is that it’s all the fault of those idiots who thought of moving everything in software, from door handles to push-buttons that cannot be pushed anymore. Remember the undetected headphones issue I had with many Linux distros? I was wrong to be so stubborn as to try to fix it in the current and future distros–and to make it a key point in choosing a distro!Īs I mentioned in almost every post tagged Linux since last June, on my oldish laptop (not the exact configuration, as mine had an extra HDD now swapped for an extra SSD) in almost every distro that is notDebian 10, the system fails to detect when I insert the headphones and continues to play through the speakers.
