I have had a chat in some forum about Chromebooks. The people there are not willing to help further because "...we only support plain vanilla ChromeOS at this forum." Full thread here: https://productforums.google.com/forum/#!topic/chromebook-central/-MXyMACfcCU;context-place=forum/chromebook-central At least someone pointed out that these devices only have stereo audio speakers (which do fine in my case) and no other "pc speaker" on motherboard. As the speakers do fine, this must be some problem in our FreeBSD kernel / audio driver, not sending the printf '\7' to the audio device. matthias -- Matthias Apitz, ✉ guru@unixarea.de, ⌂ http://www.unixarea.de/ ☎ +49-176-38902045 "Wer übersieht, dass wir uns den anderen weggenommen haben und sie uns wiederhaben wollen, kann von den Kämpfen der letzten Tage keinen verstehen.
