I'm not sure why your device can silence even nothing changed with the infoframe. Would you retry the attached patch and post the dmesg? This is just to make things more clear. I'm not against your patch in general.

dmesg attached...the first and third speaker-test invocation produced audible sound while the second and fourth didn't (the changed infoframe seems to cause the receiver to reset some internal state which kicks it into working).

OK, your device seems to work if there is a switch of infoframe, ie. coupled with the "HDMI: updating infoframe" message.

Note that the message only happens if the audio infoframe don't match up with previous one, _or_ the previous one has been wiped out by some reset operation:

Data Island Packet Data ----------------------- The contents of this buffer are cleared during function reset or HD audio link reset.

Could you try dumping the audio infoframe data at the beginning of hdmi_switch_infoframe() or hdmi_stop_infoframe_trans(), to check if the previous content have been reset to 0?

Thanks, Fengguang ---
