|
|
|
* Connect USB stick with samples which should override the default samples
|
2022-03-09 09:39:48 +00:00
|
|
|
* `ALSA lib pcm.c:8545:(snd_pcm_recover) underrun occurred`. Especially if using mp3s?
|
2022-10-16 12:01:30 +00:00
|
|
|
* It's necessary to activate the serial via raspi-config?
|
|
|
|
|
* raspi-config -> Interface -> I6 Serial Port -> No (Login Shell?) -> Yes (Serial hardware port?) -> Ok
