View Full Version : Knoppix 8.0: No sound on a HP EliteBook 8740w

No sound at all, no "Initiating startup sequence", no sound on youtube (videos play, just silently), nothing. Hardware-wise sound is not muted and not at level 0. The mouse-over of the speaker symbol in the task bar tells me "Lautstärkeregler 65". I can move its slider and switch it to muted and back to non-muted. Nothing changes.

That's the first time this happens, sound worked on this laptop with all older versions of Knoppix I tried, namely 7.0, 7.4.2, 7.7 and 7.7.1 about a month ago (and maybe a few others I don't remember).

Looks like I'm the first one reporting a sound problem with Knoppix 8.0. Can I do something to help finding the problem?

How many soundcards does your system have?
cat /proc/asound/cards

There is a thread about Firefox in Knoppix 8.0 in the german Knoppix forum: knoppix8.0 mit firefox52 Audio funktionsfaehig machen (http://www.knoppixforum.de/knoppix-forum-deutsch/sonstiges/thread6121/knoppix8-0-mit-firefox52-audio-funktionsfaehig-machen.html).
