Re: Zotac ION (MCP79) HDMI audio works on LCD monitor but not on LCD TV
I have ZOTAC A-E and this same problem. It worked with 8.10 and 9.04 backports of kernel and ALSA and PULSE, but form 9.04 on I have no HDMI sound. It is not related to driver thought - at least not directly. It was not worked with driver I used with 8.10 on 9.04 or 9.10 or 10.10, and it is not working with 270 range.
It has something to do with changes at PULSE (or ALSA driver for MPC) and it's interaction with nVidia driver.
