Subject: Toggle GPIO if ALSA playbacks begins or ends
Date: Thu, 25 Aug 2016 20:27:48 +0200 [thread overview]
Message-ID: <1472149668.24475.10.camel@embedded.rocks> (raw)
Hi,
I am looking for a way to toggle a GPIO if ALSA is about to play or has
stopped to turn an external amplifier on/off.
Can it be done using libasound or can I use a plugin or write one?
Best regards
Jörg Krause
