But HDMI video does work?
Does your HDMI display show if any audio is sent, or in which format?
What sample format did you try to play?

No, that is the SPDIF output. The HDMI sound must be driven by the same
DMA channel as the analog outputs ("Multichannel") because it is the
only one that supports more than two uncompressed PCM channels.

No, the commands sent by the driver are not shown. The logged messages
are responses from the HDMI chip.
You can show the sent commands by adding the following at the end of
the hdmi_write_command function:
printk(KERN_DEBUG "sent: fb ef %02x %02x", command, count);
for (i = 0; i < count; ++i)
printk(" %02x", params[i]);
printk(" %02x\n", checksum);

Well, the driver doesn't use C++ ...
