- libmad has been patched to avoid using a lot of stack and is not provided here. There is an issue with sync detection in 1.15.1b from where the original stack patch was done but since a few fixes have been made wrt sync detection. This 1.15.1b-10 found on debian fixes the issue where mad thinks it has reached sync but has not and so returns a wrong sample rate. It comes at the expense of 8KB (!) of code where a simple check in squeezelite/mad.c that next_frame[0] is 0xff and next_frame[1] & 0xf0 is 0xf0 does the trick ... - libmad has been patched to avoid using a lot of stack and is not provided here.

# Hardware tips
There is a possibility to have a software on/off where a temporary switch can power-up the esp32 which then will auto-sustain its power. Depending on the selected hardware, it a can also include a power-off by using a long press on the same button. The auto-power is simply acheived by using `setGPIO` and forcing a GPIO to Vcc or GND and the sustain on/off requires a button creation whose longpress is an ACTRLS_SLEEP action (see also the Sleeping(#sleeping) section.
