Mixing Different Audio Sources with Your HiFiBerry
HiFiBerry users sometimes ask us if it’s possible to have 2 programs playing music simultaneously with a HiFiBerry sound card. As the Raspberry Pi doesn’t feature something like a “hardware mixer,” mixing multiple audio sources must be done through software. Our user Steven has implemented a software solution and provided us with his full configuration. We’ve created a small guide from it, which you can check out here.
