Yeah. His point was that some AVR's don't have the option to digitize the multi-channel analog inputs - for many it's a pass through only feature.

Are the speaker settings only used for analogue outputs, or are they also used for decoding to LPCM?

The reason I ask is that I recently obtained a spare Oppo 93 which has the latest firmware and I changed all the speakers to a distance of 0 feet, because I use my AVR for room correction, and am noticing an audio sync issue with HDMI LPCM. Because of this and the fact that my ISO Oppo 93 doesn't have a sync issue and has the speakers left at default settings, plus the speaker settings do control downmixing and number of speakers, I was thinking that maybe the distance does have an effect.

I'm assuming you mean only the distance settings, because the other speaker settings (such as number of speakers and downmixing) definitely affect LPCM via HDMI: I can see the number of input speakers change on my AVR display as I change the speaker setup in the Oppo.

Also, it seems reasonable to me that since the only difference between LPCM and analogue is a DAC, that LPCM is digitally passed through the speaker settings before being split off to HDMI and the DAC for analogue. Otherwise you have to pass LPCM through only some of the speaker settings (ie number of speakers) and that can get confusing.

Huh? What firmware are you using?

I just checked the 93 with current firmware to be sure nothing weird had been introduced, and I'm not seeing this at all.

I have HDMI 1 output of the 93 connected to HDMI Back Input of a 105D. That means I can use the Info display on the 105D to see what's coming in on HDMI from the 93.

I have the 93 set to output HDMI Audio LPCM.

I checked using the AIX Audio Calibration, Blu-ray, 7.1 LPCM and 7.1 DTS-HD MA Channel ID tracks.

Regardless of how the 93 is set for Analog Speaker Configuration Down-mix or speaker enabling (i.e., speaker LARGE vs. OFF), the 93 *ALWAYS* sends HDMI LPCM 7.1 for these two tracks, and all the channel content is indeed received by the 105D in the proper place.

Mine came with similar region free device when I bought it. Haven't had any problems with firmware updates. Not as much as I'd like to, but I do watch pretty much every region B title using my 93.

(No idea regarding issues with universal titles...)

If your current, old firmware is from the brief period where ISO playback was supported, you WILL lose that. Firmware notes can be found in the first post of this thread.

BDP9x-80-0513

I had to download it to my computer and install via USB, as I did not receive a firmware update notification nor was it available to install directly to the 93 prior to my installing it manually.

Edit: Posted about it at the time on 21 June.

If you are using the ISO-capable firmware, then you have the Speaker Distance Compensation bug, and will need to use the Workaround distance settings recently discussed.

So this is probably really obvious, and I'm just dense, but ... Oppo drops the subwoofer channel by -15db. I need to raise that channel by 15 db, either on the sub or in the receiver or with a combination of the two, correct?

Then I calibrate all speakers, including the subwoofer, to a dbl of say, 75? Doesn't that remove the extra 15db I added to the subwoofer in the first place? Or is the sub calibrated to, say 90db?

^ Calibrate everything to 75dB SPL, including the Sub. Once you have achieved that, then the proper Sub boost -- whatever is needed according to your Speaker Configuration and what your AVR might itself be providing -- must already be in place.

Paragraph 1 is correct. Paragraph 2, sub needs to match level of other speakers, so 75 is your goal, regardless of how it is reached.

I use a combo of receiver and sub to get there, though in reality I haven't used a meter to check it out yet.
