menuconfig SOUND
bool "Sound drivers"
select POLLER
help
Say Y here for sound support. At the moment that's just beep tones.
Tones are played asynchronously in a poller. Check the beep command
for how to exercise the API.
if SOUND
config SOUND_SDL
bool "SDL sound driver for sandbox"
depends on SANDBOX && OFDEVICE
select SDL
config SYNTH_SQUARES
bool "Synthesize square waves only"
help
For beeping on PCM sound cards, barebox needs to synthesize samples,
which can take too much poller time for crisp playback and/or quick
booting. If your playback stutters, say Y here. This will have all
synthesizers output a gain-adjusted square wave instead, which is
less time-consuming to compute.
