Real time playback of digital audio signal from Cirrus Audio Card SPDIF input through Raspberry Pi USB DAC

Dear Sirs,

Is real time play back of digital audio signal recieved through the SPDIF input of the Cirrus Audio Card through an USB DAC connected to the Raspberry Pi possible?

If yes, than what kind of OS version, drivers, software, patches or settings are required?

Thank you in advance

Kind regards

Maybe you are searching for a realtime kernel?

It's not quite what you asked, but you can play back SPDIF audio via the on-board DACs on the Cirrus audio card. In this case the audio data doesn't go through the RPi and there is no CPU load at all.

@Tim
Yes, I know. Only wanted to make the new old kernel a little more public ;-))
