My sound drop problem saga revisited and updated!!
NOTE... I get sound drops when I use the digital sound out of my 6412 both SPDIF and optical outputs. Analog RCA output does not seem to give any sound drops.... though to be fair I have not used that source for any length of time. Why would I when my TV viewing is setup for HDTV and superior sound.
Cogeco has previously said that the sound drop was a problem of Yamaha equipment interaction with Motorola... I can now say that the problem also exists with Technics and Marantz receivers... which leads me to conclude that the problem is source (head end) or the Motorola unit and nothing to do with the connected amplifier equipment.
Why do companies always want to blame the other guy for problems??? I guess that is easier than taking the time to really find the cause, everyone is just too busy doing the everyday stuff to step aside and look at a problem with any in depth analysis. Oh, for the good old days when companies had the resources and/or the inclination to really get to the bottom of the problem. <Rant off>
Some of my recent testing makes me ask this question:
Since Cogeco has deployed the 6412 in single tuner mode.. would the sound drop problem go away with dual tuner setup??? I think it may well be solved by taking that step... see further below.
Having purchased a Marantz Receiver in the hope that my sound problems with my Technics receiver might go away... I can report that they have not. Though now that I have a higher grade receiver I can see more clearly what is wrong with my cable service audio!
The buzz I got with digital sound out from the 6412 and my Technics Receiver on channels 6/56/71/97/128 has gone away because my Marantz recognises the digital sound to be centre channel only!!
My Technics was trying to make that one sound source Dolby Stereo. The analog sound is recognised as 2 channel stereo by the Marantz.. that is the sound feed from the originator channel. I understand that Cogeco converts the analog sound feed to digital and sends it in addition to the original analog.. so for those above channels have they made an error?
No other channel that I can find exhibits that single centre channel encoded digital sound. NOTE Ch #906 shows 2 ch stereo even via the SPDIF output.. I understand that to be the audio source untouched by Cogeco.
Sound drops are still a problem and luckily today while the tech was here he could hear them... previously all I could do was show PVR recordings of them. Having changed the 6412 to a new unit I now am finding that the recorded program does not exhibit the sound drop on playback.
Could the single tuner setup be causing the sound drops??... since the live sound exhibits the drop (with PVR active or not) but the recorded sound on the PVR does not exhibit the sound drop!!
I think that is very likely the case... and am suggesting here that dual tuner setup (the way Motorola has designed the 6412 to work) may solve the sound drop problem.
I believe I am finding the sound drops to be more frequent on the digital channels (Nat Geo, BBCCA, Animal Planet) vs the HD channels... no scientific facts just an impression. Are they compressed more than the HD channels??
An aside... I have been unable to get VOD on my HD box for the last while but could do so on my regular DD box.
The tech could not understand why that was the case on looking at the diag: readings... HD box gave 217 error while all the readings suggested the box was communicating well 2 way. A couple of refreshes from the head end solved this today with no visible reason for it... the tech was surprised and could see no reason why it would just auto fix after some time not related to any change/action.
So the saga goes on.....
Is it all due to high compression of the Cogeco feed and lack of equipment power at the head end to deliver the service correctly????
That is my conclusion/fear... and I am still paying full pop for this *broken* digital TV service.
Customer support and the techs are all trying their best but it seems that middle management decisions may well be the root cause of all these problems. Are they hiding the truth from the higher ups in the company too??
It must be really tough for the techs to work with a system that they know is broken and unable to deliver the QOS while being unable to let the customer know that. They have to come out over and over and make nice to the customer, while knowing in their heart the problem has not been solved.
I have been dealing with these problems since getting the 6412 in December. I think 3 tickets for these very same problems have been opened and closed since that time..... while the status quo remains that my service is broken.
Bell were just at my building yesterday saying they had upgraded the phone service in my neighbourhood and were now able to offer superior DSL services. If only they could supply HDTV service via the phone line...
