Thanks for the tip! I did install hda-analyzer, but never ran it since other stuff came up. The sound thing wasn&#x27;t such a huge issue, because I just play the music without headphones.<p>Another problem is that the laptop has a 2.1 sound system (or 4.1 maybe, I am not actually sure?) and the outputs are a bit wonky (which can, apparently, also be fixed&#x2F;configured with hda-analyzer).<p>In short, the whole laptop is a mess. I imagine it will be fixed eventually by Linux sound drivers. I am still collecting data to open a bug report on kenrel.org, hoping it helps future people not having to go through all this… bullshit, for a lack of more apt expression.
