We are the devs involved in dCore porting, and that is one of our users report: http://forum.tinycorelinux.net/index.php/topic,18225
We verified that in few of our legacy laptops. It didn't reproduce for every laptop, but indeed in a couple of them, the temperature of the speakers reached extremes levels in few seconds, only unplugging the AC/DC cable saved them. This is a serious problem in our opinion, and we would hate to see our dCore reputation spoiled. We hate to admit, but it is *NOT* our bug, and would hate to see this bug reverse engineered into a virus/malware (on Linux, or other OS) and see ourselves blamed for it. So we would like to keep the incident quiet, and we are going to remove that thread from our forum. On the other side, we would expect any action from ALSA project in removing that tool and/or exposing the real individual/s guilty of writing that tool.
Thank you for your attentions and looking forward your feedback.
