one hw-resource for multiple processes : Raspbian

Fri Jul 20, 2018 5:28 pm

Sorry if this is a beginners question : is it possible to use a single HW resource for multiple processes?

To be more precise : I'am streaming the microphone input of a USB sound card (ALSA) to a distant IP adress (RTP/UDP). This is already existing.
So this is the process that has taken the ALSA card in the first place.

Can I now run annother process, like arecord, to record the mic input to a file or will it return : resource busy?

Thank you and friendly
