It would require an extra reboot to enable user setting after 1st update boot I believe...

Overclock can be changed/disabled without a reboot.

Yes, probably, though its not straight forward (having to wait for initial_turbo to end etc.), however I posed the question previously - if the SD card is not correctly initialised (and in a state likely to generate timeouts) does disabling any overclock magically turn the SD card into one that can be safely written to, or is it still incorrectly initialised and thus likely to suffer corruption when kernel.img is written to?

Audio doesn't always seem to get passed through. (r12669 1080 ver)

I have options for pass through enabled in xbmc.

Setup, is R-Pi > TV > Receiver.

The TV will do pass through for Dolby and decode DTS and pass through PCM.

I can see on TV if it is receiving Dolby or DTS, amp will also display Dolby if it is receiving.

I have noticed with movies. I just watch a tv show that was dolby, tv showed it wasnt being passed through but towards I notice it has switched over to Dolby and played the next episode from the start with Dolby.

What does "tvservice -a" (without hdmi_force_edid_audio) report?
Does hdmi_force_edid_audio=1 make a difference?

rbej, could you make a custom build with:
https://github.com/xbmc/xbmc/pull/2158

I think this may be a very significant improvement, but could do with some testing. Especially checking subtitles are synced and OSD behaves okay.
I'd also recommend changing "Vertical blank sync" to "Always enabled" and enabling "Adjust display refresh rate to match video".

root ~ # tvservice -a
PCM supported: Max channels: 2, Max samplerate: 192kHz, Max samplesize 24 bits.
AC3 supported: Max channels: 6, Max samplerate: 48kHz, Max rate 640 kb/s.

With hdmi_force_edid_audio=1 Dolby passes through to the receiver. (I was wrong about DTS, the tv doesn't downmix it)

Edit

TV is LG 55LW9500
I have the same problem have to force ac3 and dts only working down mixed Samsung eu55d8005 v2 tv.

Edit: fixed

I gave it a try and it seems to be smoother; I can certainly play some files that I couldn't before without using Audio Passthrough.

However, I still can't play a full 1080p with TrueHD soundtrack without stuttering, even moderately overclocked. Is this to be expected?

I also don't get any subtitles anymore, but this may not be down to the patch as I was running a vanilla rc2 openelec before.

You are not going to software decode 8 channel audio (TrueHD) on the arm.

For subtitles issue can you try "Rbej Frodo Final Version 1" and see if that works? Will show if subtitles problem is due to my patch, or something else.
Hey rbej, I've never tried your builds before but I'd like to give it a whirl until the next version of OpeneELEC is released with Frodo final. I have a 512MB Pi and I don't have a TV tuner, will the included PVR/Xvdr addons cause any issues w/o the hardware attached or can I just disable them in XBMC?
If you dont use pvr/xvdr you will not have any problems. Pvr and xvdr is disable on default.

His build worked great for me and I have no TV tuner.
Awesome thanks! Do I have to set a guires or if I leave it out will it default to 720? Have either of you tried the Sabnzb-Suite addon to see if it works? I've had trouble with it in the past in nightly builds.
