I have moved the Audio related posts to their own thread so that it can be more easily digested by interested parties. Only posts V5.12 Audio related issues here. All other V5.12 issues should be posted in the main thread.

Has anyone noticed if the audio dropout issue is resolved with this release? I have experienced this problem on my local HD channels but am still on 5.11.
Nope. I still am having audio dropout problems. Especially with the Seattle ABC affiliate KOMO when delayed or recorded. The 11 o'clock news is bad every night. But the trick play problems are few and far between. Much, much better!

I am pretty sure the Komo problems is a source related issue based on some of the other posts I have read.. I am sure Rob will bonk me on the head if that is not true... Scott.. Do you have any other receiver to compare?

A long time (i.e. well over a year or so) ago the audio issues with KOMO were their fault but I think the last round of issues is something else. I know that during the end of the TV season in May I would have problems with KOMO HD events recorded via the DishHD station but the same event via my OTA version of KOMO HD would play fine. I haven't really watched anything delayed/DVR on KOMO HD since Lost ended. I'll have to take another look.

I'll try and check out the news cast tonight.

Ditto. I got 5.12 last night on both DVRs. I can confirm that Trick Play now works better but the audio dropouts are still there. I see this mostly on recorded local Fox and ABC channels. In addition, I am now seeing intermittent (perhaps once every 2 minutes) brief image breakups on NBC with sudden camera or scene changes. This is most apparent during Prime Time and Leno. This issue was evident about a year ago but fixed with or before 4.49. It came back with 5.11 and is still apparent with 5.12.

So I recorded and watched the 11:00pm news on KOMO HD, delayed, and didn't see any dropouts. I didn't watch the whole thing but spot checked it throughout the broadcast. If there is a certain show, or maybe just national HD content, that is showing this let me know and I'll setup timers to try and test.

I have experienced the following:

Occasional audio dropouts apparent on recorded episodes of House from this past season on Fox. (I'm still catching up) If I skip back, the dropout will be gone. Also, recorded episodes of Nightline on ABC can sometimes sound garbled, as if speaking under water throughout the show.

Just a thought but both of those networks broadcast in 720P

Rob,

It is interesting but local channels in Bay Area have similar audio issues since 5.11. My 622 was on 4.49 and was working fine until 5.11 came. I never had (or better said only had minor) issues with this receiver until three weeks ago when 5.11 was installed.

The audio drops occasionally on Live TV, but recorded or delayed shows are totally unwatchable. The audio mostly drops on KTVU (Ch 2 FOX), ABC (7), CBS (5), NBC (11).

In the past days I noticed that the audio on other channels (Discovery HD, History HD) occasionally drops on Live TV (rarely) but on recorded and delayed it drops 5-6 times for 1-2 sec, in a 30 min period.

I am curious to see if 5.12 resolves these issues.

Regards,

I fail to see the correlation. Digital data is just that, digital data. Ones and zeroes, whether 480i, 720p or 1080i, just ones and zeroes. Why would the codec pick on one bitstream and not another, and why just the audio? We see the same problem here and it's hitting the 1080i channels as well as 720p. Sounds like momentary burps

Confirmed: I'm yet having audio dropouts with OTA local channels even after the update to 5.12, including PBS which is 1080i. Not with live programming, only with recorded or delayed shows. If I rewind after a dropout, it doesn't repeat itself. Meaning that: (1) it's not a problem with my receiver (otherwise it would happen with live shows too) (2) it's not a problem with my TOSLINK cable (otherwise it would happen with all other channels and in all modes) (3) it's not a broadcast signal problem (otherwise it would repeat itself after rewinding and it would happen when watching live programming) (4) it's caused by a DVR bug (only logical explanation). I also suspect that the audio dropouts do not happen with the analog outputs, only with the optical/Dolby Digital output, although I need to test that yet. Furthermore, the problem started with FW 5.11, since I'm 100% sure that the problem didn't exist with 4.49 and previous FWs. Audio was flawless until about one month ago. Finally, it doesn't look like the stream of data is interrupted -- my receiver has speaker relays that "click" when there is an interruption due to signal loss or cable disconnection. These dropouts happen without producing the clicks or changes in the stream status panel, so it looks more like the sound is muted at the 622 or there is a mismatch between audio and video streams that leads to lack of sound during the audio glitches, without affecting the continuity of the streams.

Dr. Cool has it right. I Ditto his points. The muting is momentary and seems limited to the broadcast channels. It is so brief that it usually only mutes one syllable of a multi-syllable word. But that often makes the word unintelligible. I recorded a Fox show last night for time-shifted viewing and it occurred about once per minute.

My DVR got 5.12 yesterday afternoon. I hoped this would fix the major audio issue clearly introduced by 5.11. On my ViP622, all worked fine until 5.11 was installed, regardless of the software version.

I also have major audio dropouts on recorded and delayed programming mainly on local channels (in Bay Area, FOX-2, ABC-7, CBS-5 and NBC-11) which makes the show unwatchable (not sure why but the drop is more frequent on newscasts, 10PM or 11PM news).

I did some tests last night and watched the same channel (FOX-2) on both tuners in the same time, one on channel 2 and the other on channel 6XXX (whatever the number was) and both had the same issues. I am not sure if the broadcast on Channel 2 KTVU is just linked to channel 6XXX or they broadcast from different transponders (didn't have a chance to research this yet) but they both come with the problem. Sometimes there is a slight difference between the two, the audio drops more on one than on the other, and sometimes it may even drop more or less depending on how many times I skip back and re-watch the scene. Very strange indeed.

You say that the audio may not drop in the same place if you rewind, I have noticed that there may be inconsistencies but the audio drop doesn't go away entirely.

Last night I watched a time delayed, paused for about 10 min "So you think you can dance" and the audio didn't drop (I assume this was a national, at least West Coast, feed) but the second the show ended and the broadcast was changed to the local feed, the audio started to drop continuously.

Occasionally I notice the audio dropping on other HD/SD channels but this HD local channels issue introduced by 5.11 (and not fixed by 5.12) is really disturbing, making the show unwatchable when recorded or time delayed.

Sorry for the long post...

It must be hit & miss because I was watching the same show (So you think you can dance) and the audio dropouts were all over the place. Interestingly, it was frequent and most obvious immediately after the commercial breaks that I zipped through.

I was viewing it time-shifted on the sat HD channel, not OTA.

Very strange indeed. I wonder why these inconsistencies. Now we know it is not only the local feed affected, the national (or West Coast) may be affected as well.

I also refer to the HD channels that come from Dish, I do not have OTA setup on the receiver (or the TV for that matter).

BTW, I see this issue with HDMI (receiver to LCD TV) but also on another TV via antenna out, so this is a receiver issue, and not HDMI or TV related.

I am also having the audio drop out problem on my 722. I have only seen it happen on one channel so far, my Fox local, KDFW in Dallas. I am watching live, not recorded when this happens and it has happened on local programs and network programs. This has been going on since 5.11 and is still going on with 5.12. This is not just a momentary thing at times. Lasted a couple of minutes or more on several occasions, but usually its just a brief dropout.

I have now seen the audio dropout on other channels than KDFW. It happened on KDFW, my NBC station, on a national broadcast, and I have had it on a recorded program. Audio was lost on and episode of "The Closer", on TNT for about 15 minutes of the program, and then returned to normal.

Re audio drop out issues, I was just watching a DVR'ed episode of the Simpsons (syndicated by my local Fox affiliate) and was noticing frequent audio glitches. In almost every case, the audio didn't drop out entirely, but was significantly garbled/distorted to the point of being unintelligible for several seconds. Roughly analogous to the loss in quality/bandwidth loss you hear on a cell phone right at the fringe of reception.

Join the club, Mr. Geek! This seems most obvious on OTA channels. Not sure E* has even acknowledged there is a problem. :(
