[BRLTTY] sys_linux.c:enableBeeps()

[Mario Lang]

Hi.

enableBeeps() instructs modprobe to load the "pcspkr" module.
I just found out that there are at least 2 kernel modules
that provide beeper support, that is pcspkr, which only
provides simple beeps, and snd-pcsp which provides the simple
beeps + an ALSA PCM sound device.

If BRLTTY hardcodes pcspkr, snd-pcsp can no longer be loaded since that
conflicts with the already loaded pcspkr module.

It is possible to do rmmod pcspkr followed by modprobe snd-pcsp.
However, I am inclined to think that it would be better if BRLTTY
wouldn't force its decision on which module to load on the user.

Any comments?
