I meant ALSA compress offload feature where hardware can decode the 
audio ie: it accepts compressed streams not just PCM.

See:

https://www.kernel.org/doc/Documentation/sound/alsa/compress_offload.txt

Is this already supported in GStreamer? Looking at the tip of 
gst-plugin-base alsasink only accepts raw audio. Am I missing something?

Thanks,
