Hi, I recently came across the compressed audio framework used with ALSA-SOC. Can the framework be used to send compressed audio to HDMI driver?.Like using tinycompress from usespace . thanks,

HDMI already supports IEC modes when you can send AC3, DTS, etc payloads without decoding. All you need to do is packetize the data in userspace and send the result over the HDMI PCM device (and set some control bits to help the receiver lock faster).
