Dependant on the source
The HDMI spec, since the first 1.0 version, enabled up to 8 channels of 192kHz PCM audio to be supported, which means that
decoded Dolby TrueHD and DTS-HD Master Audio can be handled. In fact, most (if not all) of the
HD-DVD and BluRay players have the ability to decode these formats and transport them as multi-channel PCM on HDMI. This is great, because quite a few HDMI AV receivers can receive multi-channel PCM on their HDMI inputs, and thus render them on the speakers.
HDMI 1.3 adds the ability to transmit
encoded DolbyTrueHD and DTS-HD Master Audio on HDMI. This adds another level of flexibility to choose where the audio is decoded (by the source, or by the AV receiver for example). HDMI 1.3 is not required to enjoy these new lossless audio formats since devices can perform the decoding in the source and then transmit the audio as decoded PCM instead.
As far as the maximum audio bandwidth of 36.86 Mbps, It has not been exceeded yet to the best of my knowledge.
