Subject: [HDMI AUDIO] How I can disable null packets?
Date: Mon, 18 Jul 2011 14:09:00 +0400	[thread overview]
Message-ID: <4E24063C.8040206@gmail.com> (raw)

Hello,

My problem is TV doesn't receive audio through jack 3.5, because my 
video card send null packets by hdmi output.

Here this part of intel_audio_dump:
SDVOC HDMI encoding            1
SDVOC SDVO encoding            0
SDVOC null packets            1
SDVOC audio enabled            1

I solved this problem in old packages (2.9.1) by intel_audio binary in 
reg_dumper folder. This binary do:

if 0 /* disable HDMI audio bits */
     dump_reg(SDVOC,        "Digital Display Port B Control Register");
     dword &= ~SDVO_AUDIO_ENABLE;
     dword &= ~SDVO_NULL_PACKETS_DURING_VSYNC;
     OUTREG(SDVOC, dword);
endif

Now this binary doesn't work — it do nothing.

How I can disable null packets in new package (2:2.14.0-4ubuntu7.1)?
Thanks.
