USB to 3.5mm Audio Adapter - The good and bad

[salada2k]

I bought one of those little adapters on ebay, such as the one you can see here: Link (http://cgi.ebay.com.au/USB-to-3-5mm-Audio-Adapter-for-Dopod-S1-HTC-P3450-Dash_W0QQitemZ370065166062QQihZ024QQcategoryZ20336 QQrdZ1QQssPageNameZWD2VQQcmdZViewItemQQ_trksidZp16 38Q2em122)

Couple of things:

- Music - it now sounds brilliant through my personal headphones - the ones that come in the box with the diamond are indeed complete rubbish. But that was fairly obvious anyway. I'm impressed with the quality of the diamond now.

- Taking calls. Now we have a BIG PROBLEM. When a call comes through, the audio is routed through to my headphones as you would expect. But the problem is that the diamond must think there is a microphone attached as well, as noone can hear me speak until I pull the headphones out of the diamond and it's internal mic kicks in!! Then when the call is ended the music starts blasting out of the speaker of the diamond while I'm madly trying to plug the headphones back in, amidst getting all sorts of annoyed looks from people next to me on the tram that WERE sleeping until I woke them up..... Woops :D

Does anybody know a workaround for this? How can I make the diamond think there is NO microphone plugged in when I'm using the headphones?? Will I have to short some pins on the connector...? Anyone have the pin layout for the 11 pin HTC connector? Or is there an easier way.... Help from the experienced is appreciated. Cheers.

OK so here are the pinouts:

So it would seem that 'disabling' pins 7 and 12 on the adapter might do the trick.... Or maybe they already are disabled on some of the adapters out there..

It's going to be hard to do on such a small thing... Does anyone know a way to trick the OS or disable it in the registry somehow??

I got one of these http://www.amazon.com/Synch-Charge-Stereo-adapter-microphone/dp/B001A71SMQ/ref=sr_1_2?ie=UTF8&s=apparel&qid=1215060921&sr=8-2 from Amazon and it works like a charm. You might want to try this.

Have you try this adpater to listen to radio without the headphone. By plugging in this and set the radio to speaker phone.

what about that (http://www.expansys.fr/p.aspx?i=150195) ??
you can plug any 3.5 headphones you want, it works for the fm radio, and you have a mic so you can talk when receiving a call without having to do the unplug replug acrobatic move you used to ....

Hm... I plugged in mine (I use the RC e100), and somehow all other headphones (also high quality one) I have are all worse then the one within the box =( very annoying, as the the htc headphones are far to big and ugly =(

Also the whole audio stuff is poor on the diamond - I read s.th. of an audio booster bug, but no way to cure it =(

What have you done to have such a good qualtity?

[salada2k]

Thanks for all of your replies.

I ended up going with the RC E100 as you suggested and some other people here (http://forum.xda-developers.com/showthread.php?t=399616) seem to think they work well. Well, they definitely do!

I've plugged my Sony's into them and they sound awesome. Really impressed with the audio quality now. Just have to figure out where to hide all the cable!! 2 metres + hiding inside my jacket! Might have to get the scissors and soldering iron out and re-work it...

The only problem is that the supplied driver with the RCE100 does not install on the diamond, or maybe its a problem that I'm using Vista with Windows Mobile Device Centre instead of Windows XP with Activesync. I will try and install the CAB file manually.

The Play/FF/RW on the headset only controls the built-in audio player in TouchFLO 3D, need to figure out how to make it work with Core Player.... And to answer you question Basthet, it sounds much better with Core Player, no audio booster bug, it has built in pre-amp and also equalizer and you can make your music sound very very nice with it. Highly recommended. It does not cure the little skip you hear in audio tracks; it is now clear this is an Operating System/Hardware issue.

I know that acrobatic move that you speak of, and it made me laugh to see that I'm not the only one running into that problem. Happened to me while official exams were being held in the classroom nearby, nearly got me expelled. :P
