ratmice, did you fix this yet? I'm hoping you could do a quick hex edit of the UMC-1 flash upgrade files, identify the location of the anomaly, and release a firmware update by EOD today. Thanks. j/k (obviously). I was just assuming, if you'd made it this far, you were on quite a roll and might as well keep on going! If I had a UMC-1 here, I'd help you test. I'm hoping some others will click in and read this thread. If you're reading this, and have a UMC-1, this test is quick and easy. Go add lip sync delay and play a 2-channel digital source. Thanks, everyone, who gives it a shot, and thanks, ratmice, for all of your Sherlock work. I've almost got the FW ready to release. I've added wireless networking, HDMI 1.4 support and PLIIz as well, just trying to get the 3D to work right.  p.s. it will also include backwards compatibility for PS2 games on PS3 ;D What, no XBOX 360 support? Nice detective work. I did some of my own last night. I put in the Akria BD (mastered at 192khz), again last night and noticed that the UMC display said 48khz. I didn’t notice any audio drop outs when I fast forwarded or rewound. So I went into the audio settings of my PS 3 and noticed that PCM 96khz and 192khz was not selected. So I selected 96khz and replayed the disc. I did get audio dropouts when I fast forwarded, rewound or paused the movie, but the UMC-1 would usually reacquire the audio after about 3 seconds. I went back into the PS 3 settings and selected 192khz and then again played the Akria BD. Now I got audio dropouts when I paused or fast forwarded or rewound and the UMC was unable to reacquire the audio. So this seems to be very similar to the same audio dropout I am experiencing with music. It seems that as long as the frequency is 48khz, everything is fine. But ANY frequency other than that seems to give the UMC some trouble. So just to reiterate my findings from last night: Akira BD at 192khz1. Output at 48khz from PS 3 – No problems with audio 2. Output at 96khz from PS 3 – Audio dropouts, but UMC was able to reacquire audio after a few seconds 3. Output at 192khz from PS 3 – Audio dropouts, UMC unable to reacquire audio. |

Output at 192khz from PS 3 – Audio dropouts, UMC unable to reacquire audio. I have that disk at home, and I used it to check the timing issue. I will have to check for the audio dropouts at the higher resolutions as I haven't noticed anything like that, yet. Now that I think about it I may have been playing it on the Oppo rather than the PS3 - I'll try both. |

I thought 96/24 was the highest resolution the UMC-1 could handle, and this for DTS encoded material?

I thought 96/24 was the highest resolution the UMC-1 could handle, and this for DTS encoded material? I am happily bitstreaming TrueHD 5.1 @ 192 kHz right now. So it seems that the UMC-1 is capable of that bitrate all around. Akira BD at 192khz1. Output at 48khz from PS 3 – No problems with audio 2. Output at 96khz from PS 3 – Audio dropouts, but UMC was able to reacquire audio after a few seconds 3. Output at 192khz from PS 3 – Audio dropouts, UMC unable to reacquire audio. I tested the Akira disk at home with the Japanese 5.1 TrueHD @ 192 kHz and did not notice the dropouts. After FF/REW there is maybe a sub-second delay while the audio stream restarts. After a pause it starts immediately. This is with a slim PS3 bitstreaming. I'm not sure where your delays are coming from? Are you by any chance sending LPCM and not bitstreaming? I could try that if it's the case. Well, answered my own question, as I DO see the audio dropouts when sending LPCM over HDMI @ 192 kHz and it will not reacquire the audio steam. Switching inputs fixes it. |

See my previous post. you can get 5.1 @ 192 kHz.

OK. New info. In some pretty extensive testing this morning, the problem only seems to arise when you have a non-zero (non-auto) lipsync setting on the input you are using for playback. When I initially noticed the problem I had just thrown a CD into my DVD player to quickly play it. That input had a lipsync setting at 125ms (any setting will produce the problem). Again this is with 44.1 (CD) or 88.2 (SACD) 2 channel material with the UMC set to any mode but direct. You get a rhytmic "beating" or clicking sound. The sound only appears from the right preout connection. Oh yeah, it's also limited to digital inputs (HDMI, OPT, COAX) - analog is fine. If some folks would check this out it may help verify that it is a reproduceable problem. I did some testing on this today with the UMC connected to PS3 slim via HDMI. The audio mode was set to stereo, and I tried both 44.1 and 88.2 output with two different CDs. I don't hear any clicking out of the right channel, and I went right up to the speaker to check. I do have an old Sony CD changer that I intend to test, but I can't find the optical cable to hook it up yet (just moved recently). |

Sorry, gotta ask as you didn't specify. I'll have to play with the PS3 a bit more, I tested it before I figured out the lipsync deal. add: just played around a bit and I do get the problem with a PS3 slim set to bitstream 44.1/88.2 material over HDMI. |

Yeah, I forgot to mention I tried several different lipsync settings from 5-30. Also, PS3 was set to bitstream.

It also is unmistakeable if you play a test tone from CD, I used the stereophile test CD 1. If I did it right.....44.1 cd/stereo setting/hdmi with lipsync produced no irregular sound from an oppo. |

Would you mind checking what happens when you switch to bitstream, if you don't mind? |

On the ps3 bitstream it shows 48khz? - On the oppo same disc shows 44.1,bitstream,with sync at 1 on umc,I hear nothing(ticking? or unusual in any speakers.This was with volume on 20,soft passage.Hope that helps .

There's a setting on the PS3 to output audio at either 48 or 44.1/88.1/176.4 I don't remember exactly which of the billion menus it's on though. so you can tell the PS3 to out put 44.1, you may also have to go into the audio setup and de-check (is that a word?) the other higher resolutions. I know this is a PITA, so I don't blame you if you blow it off, but it would be great to get confirmation. Thanks for helping. |

Ok.set the ps3 to 44.1,sync to 1 on umc bitstream.I heard no odd sounds,I did have the first second of audio cut out on each track,I had track not start until paused/played and generally a disaster,not to mention it sounded worse than 48 to my ears.The 48 setting sounds great,works flawless,is there some reason for the 44.1/88.2 etcc.. setting?I don't like it.

Actually the 44.1 kHz is the native sampling rate for CD, and 88.2 is the native sampling rate for SACD. On any other source you would not be able to select 48 kHz at all. In other words your standard CD player is sending out 44.1.
Now the explanation of why 48 works, and sounds better, than 44.1 I will have to leave to those much smarter than I.
p.s. Thanks again for taking the time to do this, I know from personal experience how painful it is to tweak all the PS3 settings - even remembering where they are is a chore.
