Sound cuts out every so often when using Coax Digital In

I have my Satellite and Xbox360 running into my TV using HDMI, then using my TV's Coax Digital Audio out to connect sound to my Philips receiver.

However, every few minutes, the sound cuts out, and the receiver display acts as if its recognizing the signal for the first time. Posts up the DOLBYPLII message, then the sound comes back in and it goes right back displaying DI, which is what it displays the whole time the sound works flawlessly.

I tried bypassing the TV thinking it may be the culprit and hooked up my other dvd player to the receiver using the digital in as well. Same issue. Every few minutes its like it reconfigures what its decoding, and the sound cuts out while it figures it out. But the sound is constantly coming, cutting out mid song, or dialogue sometimes.

Could it be my wires? Thats the only other constant. I used a high quality Sony Digital Coax wire to connect the devices ($15 for an rca cable... gag me).

I have the same problem with the HTS 3544 unit.  It cuts out about once a minute when using the direct input from the TV.  Is the only answer to replace the unit?

    I have the same problem, here is my setup.

    Oleiva 42" LCD HDTV

    Comcast HD DVR Cable Box (connected to TV via HDMI)

    Xbox 360 (connected to TV via HDMI)

    Philips HTS3544/37 DVD home theater system

    It does it alot when I'm using my xbox 360, right from the start up and just going thought the dashboard blades, I get no sound of the blades moving unless i move through super fast, in which it gets the sound of the last two blades, missing the first 3.

    I was using just the analog Red and White cables earlier and it had no problem. But only does this when hooked up to Digital input coaxial. I also spent $15 on a Sony Digital coaxial cable from target. But I highly doubt that is the problem.

    i was having trouble at first just getting sound from the coaxial (little did I know that the TV can actually control the volume unlike using analog). Before I figured out that I when to the tech support website and did what I thought was a firmware upgrade, unfortunately I already had a more current version on the system than the website has, so I don't know if it was already fixed in the latest firmware.

    To check your firmware, turn the system off, then on then open the DVD tray and hit display on your remote. This is what mine read before I up/downgraded the software:

    Ver00.28.00_70531_01 Region: 1

    Servo: 0F.60.00.00

    8032: Risc:

    now it reads:

    Ver00.27.00_70517_01 Region: 1

    Servo: 0F.60.00.00

    8032: Risc:

    The ver and Risc are now lower than what it was. Check and see what your software reads so we can see if you're running the latest version and still having the same problems...

    I upgraded the firmware on my HTS3544 and it solved my audio problem, but only for a few weeks, then it again went back to the cutting out every minute or so.  I have the same version code:

    Ver00.27.00_70517_01 Region: 1
    Servo: 0F.60.00.00
    8032: Risc:

    I re-installed the firmware and it still cuts out.  I don't understand how it was fixed temporarily, then reverted back.

    This happens only on the Direct Input from the TV.

SOURCE: Sound cuts out every so often when using Coax Digital In

Just so you know, the "rapid replacement" unit Philips sent me WAS rapid, but it was a refurb unit, complete with scratches, and it had the same problem as my original unit.  The sound still cut out when using the digital audio coax in.  I sent it back and returned the original to Target.

Intermittent sound

Try a digital coax or optical for audio and see if that helps, you will still get all the benefits of HDMI video but perhaps no audio issue,ensure your kit is running up to date firmware. If that don't help play with the connections try a different HDMI cable, different VIDEO source or try the connections with a different AMP .
Hope it helps... :)

I'm not sure what you mean by "run surround sound from this tv" . If you are using an antenna for HIDEF you would run an optical cable from the tv to the optical input on your receiver labeled CD. If you are using a cable box or using a blu ray player simply run a coax cable from said box or player (digital out) into your receiver labeled DVD and run the HDMI cable straight into the back of your tv strictly for video. Note that some recent budget players have omitted digital audio outputs entirely. Hopefully your player has them. Hope this helps. Feel free to ask for clarifications.

if you have a coax digital out on your tv, why not use that, you have coax, optical, and hdmi inputs on your reciever, but the easiest, low cost way is the coax

No audio running TV through Denon AVR 1910

I had the same problem. You're not doing anything wrong. the thing is you can't (I don't know why but the owner manual says it) have sound going to your tv AND your HT speakers when you're using HDMI. You should try going to input setup, choose hdmi audio out to your TV instead of the speakers, and then run an optical cable from your satellite to your receiver, assigning it to the TV/Cable input.

MX 3950D Philips - PS3 no sound

Aside from the xbox360 working via the coaxial digital cable. I got the PS3 to work this way.

I had to use the supplied SCART > (Y-video) (Red-Audio) (White-Audio) cable. Basically plugged this in from the PS3 directly to the MX 3950D Aux (Auxiliary) audio input.

On the PS3 audio settings menu, switched from HDMI to the 3rd option SCART.

Turn on the MX 3950D and set to Aux. Bang, got sound again.


I missed this cause I "assumed" the video/audio cable that came with the PS3 was a HDMI to Audio/Video cable, and didn't even see the SCART port in the back of the PS3. So I thought I didn't want to lose 1080p ..etc etc. Anyways. MX 3950D still good =)

You have almost answered your own question.
The HDMI does not output sound so use it for the video only and run another cable for audio,
be it RCA or Digital Coax.

Sony STR-DA5300ES Audio Problem

I am posting this to try and get everyones audio problem for this receiver fixed. If you only connected the HDMI cable to the 510, you will not get sound. This receiver passes through HDMI only, no processing of audio. You must either connect a fiber optic or digital coax to the 510 for that respective HDMI input from the BD player, the DVD HDMI only accepts digital coax, and the Video2 HDMI only accepts fiber optic. If you BD player does not have digital coax out for audio, you must move the connection to Video2 HDMI and connect fiber optic to the Video2 fiber input. Sony butchered the whole purpose of HDMI with this receiver. Hope this heps you. By the way, it is hardware, no firmware update will correct this.

Sound cuts out every so often when using Coax Digital In

solution to Both our problems is this, call Philips, "it just so happens that we have a rapid replacement program for this particular system"-"there seems to be an internal electrical problem", so I'm sending it back to them.......

Xbox connectivity problem

As dumb as this sounds here is the mistake Sony made. The receiver does not process sound from the HDMI, it will only pass through that data to you TV. So you will not be able to get sound from your 5.1 speaker setup if you only connect the HDMI, you have to use the matching audio input for that respective HDMI input. Make sense? So the HDMI DVD Input must have digital coax for sound, HDMI Video2 must have fiber optic for sound, and there is another fiber optic port for the Sat input. Yes thats right, if you have 2 HDMI HD components and each only has fiber optic(neither one has digital coax) you cant hook both up properly the way you would think. Sony made this receiver poorly, turning High Definition Multimedia Interface into High Definition Multimedia Except For Audio Interface.
