Hi, We're developing a platform where we have SPDIF output. And we want to SPDIF AC3 playback (non linear PCM). Our CPU is a kind of ARM architecture one and it has a SPDIF that can support AC3 passthrough playback.
I've already know that ALSA can support SPDIF AC3 passthrough playback like follows, http://www.mythtv.org/wiki/Configuring_Digital_Sound_with_AC3_and_SPDIF But, I can't find that any ARM architecture CPU can be supportable for SPDIF AC3 passthrough playback.
Are there anyone who have a SPDIF AC3 passthrough playback? or anyone who know the clue about SPDIF AC3 passthrought playback supportable on ASoC?
Our SPDIF already can support on linear PCM playback. But we have no experience in SPDIF AC3 passthrough playback. Just changing register setup from linear PCM playback to non-linear PCM playback is enough? Or any reference code on ASoC for SPDIF passthrough playback?
Any hint would be greatly appreciated. Thanks.
