Sony forum: Sony TV sound issues

By your remarks, you obviously got a raw end of a deal w/ Sony. And it sounds like that it is leaving you scarred for life.

I've already downloaded that firmware & haven't noticed anything different at all. So, open for some more suggestions.

I have 4 other Sony lcd tvs that all use the same set-up with dish network hd boxes and a single hdmi cable. And there is no audio diffrence between the non-hd channels and hd channels. I Have a brand new KDL-40SL150 that has audio issues. A drastic change in the audio level from hd to non-hd channels. I spoke with sony tech , went through the troubleshooting procedure with him. no fix. sent me to a repair shop. The hd side of the tv has its own audio amp. As I understand it; it is a common problem with some of the newer sony's. As a rule:if you can hear a noticable diffrence in audio levels between the hd and non-hd channels. There is a problem

Every so often the sound will start getting static and then disappear, it comes bak after a period oftime but can get it back right away if I hit skip back on my DVR and all sound is back. This happens on live as well as recorder programs on the DVR.

I want to thank you for alerting us to this fix. I downloaded it last night, and it immediately stopped my sound interruptions when using HDMI cables. I am not sure how well it would work with other problems, but there is no need to curse Sony on this one. It works well.

There has been a problem with the sound
on sony's and other models also.The HDMI
cable connected to the set top box,direct tv,dish
or cable.try googling the model number of
stb and find user manual.And set output parameters.
Hope this helps.

Having tyhe Same issue, bought from Best Buy Taylor MI. Also got the Geek Squad 4 yr warranty. They replaced the Audio Board last week, it improved the intermittant sound but didn't fix it completely. Get this- the audio board the tech removed from my brand new TV had burn marks that were circled in blue marker- meaning either Sony installed a know bad board at the factory or Best Buy is selling remanufactured TV's as new. Called the Geek Squad again and they are replacing the audio board again. Geek squad says they need 4 total attempts before I can get another tv.

I have a new Sony Bravia that also has sound issues. Not only does the sound cut in and out but also gargled like the aliens are remarking about the program material. I can switch to receiver and surround speakers and it correct the issue thus knowing it is the TV. I am so disappointed and will be calling about it tomorrow. I have a Uverse cable box so how do I download the new software update?

I have the same issue since I switched from Comcast to ATT. The sound is "fuzzy" on the HD channels after the TV is on for about an hour,but not on the normal channels. It is EXTREMELY annoying. None of the advice I get seems to work.

I have a cheap Vizio that I bought in Target in my bedroom and the surround sound is fantastic. I'm sorry I wasted my money on Sony.

Even I am facing a similar problem I purchased a Sony Bravia KLV52EX 32 inches Full HD LED TV on 10th March 2011 from the Sony showroom in Amritsar. Initially I was using the standard Dish TV st top box with which it was doing fine. But, after I switched to a Dish TV HD (High Definition) set top box 2 months back, I started noticing sound problems. The video is alright, but there is no sound. The sound then comes back after switching one channel up or down & sometimes it does not come even with this manoeuvre. This sound problem is very irregular & I have been experiencing it now since the last 2 months. I called up the Dish tv people, & they changed the set top box & even the HDMI cable, but still it was persisting. Then I noticed thrice that sometimes there was no sound even in the DVD player attached to the TV when no sound was present in the TV too. I called up sony customer care explaining to them my problem. Initially they were not convinced & were blaming Dish tv for the sound problem, but when I demonstrated the sound problem in front of them with no sound coming even from the DVD player, they were convinced & took the TV to their customer care shop for a detailed analysis of the problem. Then after 1 week they called me up telling they could find no major fault in the TV as to why the sound stops suddenly & that they have even changed the sound board in the rear as it is within warranty. They suggested to me the reason for the sound problem could be due to incompatibility of the Dish TV software with that of the Sony TV & suggested me to get an Airtel connection.Sometimes, when the sound is absent, I see the message 'Unsupported Audio signal please check your device output" When I suggested to the Sony people for a replacement, they refused citing that LCDs can't be replaced The problem is still persisting & I am now at my wit's end. Kindly give me some helpful advice regarding this chronic problem.

I have a 52 inch Bravia, luckily bought service plan. First incident was pic and sound flickered until both went out, changed the channel and it worked, had hdmi panel changed, after getting back entire pic goes out then comes back on, power supply replaced , received tv back and the tv started loosing connection the would get it back in about 10 seconds. was taken to shop and changed hdmi board again, still same problem.back to shop and then returned a week later and after about 3 hours it started again. It would drop signal then after 10 seconds would come back on.Started while having Direct tv then changed to att and problems continued.put different tv in place of 52 inch ran for a couple of weeks and no issue. Also did notice that the tv is a lot warmer than any other tv ever owned. Now waiting for geeksquad to get back to me to see if they will replace set. So in all the tv went to shop 2 times and technician came to house 3 times which is five tries.One of the problems is the problem is diagnosed while talking to a geeksquad member, the request is made to repair shop, part sent to shop and replaced even if it is not the actual problem. There should be in shop troubleshooting rather than over the phone troubleshooting and just part replacement.

Thks. for your query. I first thought it was my imagination; then decided I needed a hearing test.
Never thought it could be my television. My first big LCD tv. I chose Sony because it was a reputable company. With no longer under warranty, and on a fixed income (now retired) I have to tolerate this nuisance. My son is planning to set up my surround sound so maybe this will help.

Thanks to all who posted resolutions to this problem. I have a Sony KDL-40WL140. I've had the TV for about 3 years with several different cable companies and box types, and never had a problem until my cable company came out yesterday and swapped out my DVR. They didn't change the HDMI cable - just the box, so I have no idea why the problem just started, but this intermittent muting is driving me crazy. Since I have a DVR on the TV, I can rewind to catch the audio I missed, but it is annoying. I followed the instructions in the fix, but my current software version (HH-D-QM-B-CJ) didn't look anything like the one shown in the fix, so I called Sony - 800-222-7669. They are sending me a flash drive (no charge to me) with the update on it and instructions on how to install it. They said it will be 7 - 10 days though, so if I can't deal with the issue before I get the flash drive, I will try downloading the software myself.
