This is just a warning. It means that the pcspkr kernel module can't be modrobed, which, as far as brltty is concerned, isn't a problem. It might be a problem for the user, though. Brltty plays what we call alert tunes for events the user might care about, e.g. trying to navigate beyond the edge of the screen, wrapping to the next/previous line, skipping over blank lines, etc. The default is to use the PC speaker to play these tunes. Its tune device can, however, be changed from within brltty's preferences menu to other things, e.g. to play PCM audio via the sound card. Additionally, the about-to-be released version (5.3) of brltty contains a new feature that helps overcome a related problem. Wthout a physical PC speaker, or without the pcspkr kernel module, the regular console bell can't be heard either. Since a blind user can't see a visual bell, being able to hear the console bell is important to many. Brltty has a new setting called Console Bell Alert. If this setting is enabled then brltty listens for Linux console bell events, and plays them via its current tune device. So, with brltty running and this new setting enabled, and with the tune device set to PCM, the old familiar console bell can again be heard via the speakers, headset, or whatever the user is using. >My os is Raspbian (Raspberry Pi modification of debian) and 'modprobe >pcspkr' command says : "modprobe: FATAL: Module pcspkr not found". So that's why brltty can't install it either. That's exactly what it tries to do. -- Dave Mielke | 2213 Fox Crescent | The Bible is the very Word of God.
