Got my MHL cable... no sound

**preViously** · 07-21-2011, 11:37 PM

My MHL cable was delivered today. It works great displaying what is on the Evo to my non 3D tv. Even the Green Hornet is rendered very clearly in 2D without me having to do anything special. The problem is there is no sound! Does anyone know if this is expected? Makes it sort of useless for movie / videos. Btw, i purchased the cable through Expansys.

**preViously** · 07-22-2011, 12:38 AM

I would call whoever you got it from and let them know of the problem then ask for another one. Every one I have seen is out of stock so I know not too many people have them. Could be a major bug so be sure to fill them in.

I got my MHL cable from Expansys and I can't get it to work. No video, no sound, nothing. I plugged the microUSB end into my phone, plugged my charging cable into the side of the MHL cable, then plugged my HDMI cable from my TV into the other end of the MHL cable. Nothing. That's how you're supposed to do it, right?

When you plug the charging cable into the side of the MHL cable and you plug that into your phone, does your phone show it as charging? Mine doesn't.

**preViously** · 07-22-2011, 12:53 PM

That it's how I got mine to work. It only works if the charging cable is attached. It shows as charging and a notification comes up on phone stating hdmi is connected.

The power cable must be attached. Try rebooting your phone too.

Same problem with the T-mobile cable I got for my HTC Sensation today. Please post if you find a solution.

**bbarend** · 07-26-2011, 09:14 AM

I was dumb enough to buy the Sprint one. I also have no sound.

**bbarend** · 07-26-2011, 09:52 AM

As a temporary fix, the headphone jack still outputs sound. Will be an inconvenience travelling.

**bbarend** · 07-26-2011, 07:20 PM

Hmm HDMI sound works on the new TV upstairs. Apparently I'm missing something.

I got my MHL cable from the T-Mobile store yesterday and used the 50% off coupon. Hooked it up to my Vizio LCD and was able to stream Netflix and SprintTV. Worked great.

**XandroidX** · 07-27-2011, 12:19 PM

where did you get the 50% off coupon?

**devious101** · 07-27-2011, 01:30 PM

50% off coupon right here. Good till 7/31. Got the Adapter for $10. Printed it out and went to the T-Mobile store and made my purchase.

**preViously** · 07-29-2011, 03:40 PM

Has anyone come put with a solution to this? ... besides using headphone jack? I still haven't been able to get it to work. Thanks

**preViously** · 07-29-2011, 04:29 PM

I called Sprint support. They told me to call HTC because it's a phone issue.

I called HTC support. After powering off and on the phone and it still not working, they stated I have to reset the phone and said there is nothing else they can do. They said they had no record in their system of anyone else reporting this. If you experience this issue, please call HTC so it's recorded. I'm thinking this is a software bug.

Not too happy with the HTC support today.

**CarrieK** · 07-29-2011, 07:09 PM

Went by the Sprint store since one was not to be found around here at t-mobile or anywhere else. They gave me a 25% discount, added it to my bill and had it shipped to me for free. Should be here Monday. Pretty cool of them!

Paying more than t-mo's 10.00 instore but cheaper than ordering online from t-mobile for full price and then paying tax and shipping.

**XandroidX** · 07-30-2011, 01:15 AM

thanks to devious101 for the 50% coupon I just pick up my MHL cable at T-mobile store for 10 bucks! Worked great on my monitor so far will test on hdtv soon

**preViously** · 08-18-2011, 10:19 AM

I have not been able to get sound from my MHL cable still, when connected to my TV. Has anyone confirmed that it should work with sound and video? Thanks

**bbarend** · 08-18-2011, 11:46 AM

I have tried it on different TVs and it seems to have something to do with the TV. Perhaps there is a a weird formatting issue. My off-brand TV gets no sound, but my Samsung does. Very odd.

Yes. I just got the MHL adapter from Expansys and can confirm that the HDMI connection transmits both audio and video. Its required to plug the power cable into a wall adaptor, not a PC usb port. I used the OEM HTC charger with the MHL and it worked fine.

Now if I can only figure out what video standards are required for the 3Vo to play.

Some where else (possible XDA) I thought I read that this was related to the SpiderMan game. Have you played SpiderMan and when playing turned the volume all the way down? If so I think the solution was to start SpiderMan up and turn the volume up in the game itself then quit the game and your HDMI sound will work.

Let us know if this fixes it.

I bought an T-mobile HTC Sensation 4G. I also bought a Menotek Micro USB to HDMI MHL Adapter to connect to my HDTV (Samsung). Like a number of you, I have the problem that the video shows up beautifully, but there is no audio, except via the 3.5 mm headset jack. I was wondering whether there is some kind of toggle that directs the sound output between one of three places: 1) the phone speakers (pretty feeble), 2) the headset jack, 3) the audio link on the MHL adapter. One of the reasons I think this is the case is that one time when I connect the adapter to the HDTV, audio did work. But, never again. This suggests that audio can be transmitted via the adapter and that some switch has been switched on or off unintentionally. I noticed in past threads that others were talking about a headset toggle problem with an older version of Android. Anyone have any insights/thoughts on this?

Update (9/4/2011): I sent the Menotek adapter back (I bought it on Amazon), and I received a "new" one a week later. Unfortunately, it behaved identically to the first one. It worked initially, then never again. Like the first one, the new adapter does play sound out the 3.5 mm headset output. Once again, I am wondering whether there is a software toggle that is used (intentionally or unintentionally) to switch the audio output among the possible paths.

Last night, I called Fry's Electronics to check whether they had a microusb hdmi mhl adapter, and they said they had three in stock. So, I drove on over. To make a long story short, after one and a half hours looking all over the vast shop -- assisted by five separate shop assistant and even the manager -- I was unable to find the adapters. It was unclear why the inventory system indicated that they had three in stock, when no one could locate them.
