Expose Analog audio connections?

Questions and discussions related to Inforce 6540

I'm working on a hobby project using the 6540 as the brains of an in-dash automotive headunit. The board has a 'headphone' jack for audio, but I'm really more interested in exposing 4.1 or 5.1 analog output?
I assume I could use an audio extractor on the HDMI port (my screen is currently HDMI), but that seems like an ugly hack. I could also try an add-on USB sound card, but why bypass the audio capabilities of the APQ8084 itself?

Any suggestions?

The IFC6540 does not have any exposed 5.1 audio out connections. You could use a USB sound card to access the sound card, but as you mentioned you would not have access to the onboard WCD codec.

Another option is to use the IFC6501 SOM which has built in 5.1 audio out capabilities.
