Will WP8.1 Update 1 will enable aptX for existing phones also, or it will be for the new phones only

Great I was wondering, I too have the same receiver, have not hooked it up yet, but most people claim that APTx you here much more bass, so that should be an indicator for others to look for on non cyan 1520 devices.

I was there was an indicator to tell us, but that's not even available on android... You have to dig deep in debug logging with certain options enabled in source to get whether its using it

1520 w/ cyan 8.1.1

Only thing that pisses me off about the dev preview is the profiles for Bluetooth got jacked, on official 8.1 cyan when I get in my car, and connect to my internal head unit Bluetooth (not btc 450) it would auto start the paused song and I could use the next back buttons for track skipping, but on dev preview it breaks it. Skip does not work and also if playing music and using nav or Cortana takes over to Rea a text it is just dead air, had to switch the option in Bluetooth on the phone advanced menu for trouble with voice and it fixes that, but skipping and auto play on connect stop working.

Have not hooked up the 450 external receiver yet, do you have these issues with that device on 8.1.1?

Just a note about the above, tested the 450 receiver just now and it's working fine with play / resume, skip / next track... So its only my head unit that had built in Bluetooth that has this issue, I do think the 450 sounded better then my built in Bluetooth as well.

I understand. No, there is no indicator that I am in fact streaming over apt-x. I have a non-8.1.1 Lumia 925 and 920 that I've crossed referenced. I'm hearing a much wider soundstage, more robust low-end, and cleaner highs after the update. My music collection consists of FLAC files that are converted to WMA Lossless and imported to my phones in JRiver Media Center. My Kinivo is routed through a Fiio E17 before it hits the aux-in jack of my car stereo.

For whatever it's worth, I'm a musician that's logged countless studio hours and I trust my ears, but you're absolutely right that audio quality is subjective. If you asked me my opinion though, I'm definitely streaming over apt-x.

Can you post your sample

Hi,
As I mentioned in the title, would we get aptX support on our existing phones also?
It would be great if some experts can shed some light on this.

As far as I know, aptX is a codec, so it might not need new hardware support. But for the firmware, I don't know.
So actually there are two questions here.

Will it work on current hardware?
If yes, will it require any specific firmware updates from OEM? (if so, getting only the preview won't enable it)

Thanks,.
Mahesh

apt-x is working with my Lumia 1520 running 8.1 Update 1 Developer Preview and my Kinivo BTC450. I'm playing lossless WMA files to my car and it sounds so much better.
