Well, we have no other option than doing a live test to demonstrate. You already have presumably all the correct gear to test it, from source to sink. Just try and check for yourself, to see if aptX lossless indeen downsample things or switch to Adaptive lossy.

This is from O11111's doc. Per qualcomm docs, 16/48 will be downsampled and streamed losslessly. Anything else like 24/48 or 24/96 of course will be chopped (downsampled) lossy, but still will be transfered via 16/44.1 aptX lossless stream.

1) For any content above 16/44.1, it will be downsampled to 16/44.1 (provided the link quality is good enough for 1.2Mbps). This is still superior than 24/96 Adaptive lossy. aptX Lossless will simply not drop into Adaptive lossy just because the content isnt exact match. 2)Of couse when the link...

This is simple not true, i dont know where you got it but qcom clearly stated they will downsampling everything to fit the bandwidth. Also those are processed at the source (laptop, smartphone,...) and not the sink (QCC chip).

Source dont need to be exact as they will get downsampled to 44.1 once detected.

What i means is when aptx lossless r1 is running, it will change the sampling rate to 44.1khz (versus 48khz/96khz aptx adaptive). Thats why i asked you to check in dev option. FYI, i am the one that written the whole ramblings about aptx adaptive version on reddit :ksc75smile:

Nice, you should check in developer option to check if it switch to aptX Lossless when playing some music.

Off topic but almost every BE200 out there is the non vPro version (NGWG.NV). You can check on the card itself (MM: 99C472). The Vpro version are super rare. The reason its not working on AMD is just pure artificially limitation (device ID check).

Got told from the engineer handling the demos at their launch event in October last year.

I think your right hook is malfunctioned. I tear down a set of broken UTWS5 and found no battery management chip inside the earhooks, so the battery report maybe come from the main QCC5141 chip itself. If its indeed broken then there is no fix. Quality control is bad. @FiiO please update the...

Joke aside. aptX Lossless can definitely deliver lossless 16bit/44.1khz at 1200Kbps bitrate. 1411Kbps is the bitrate required to deliver bit-perfect stereo 16bit/44.1khz, so you do some fancy math (lossless compression) to reduce the size needed to deliver. Per Qualcomm researchs, almost every...

Also from qualcomm, latest QCC5181 only supported 44.1kHz aka first gen aptX Lossless over A2DP. same with LEA, 48kHz.

Dont trust the marketing paper :triportsad: Im talking about aptX Lossless over A2DP For LEA (LE Audio), the best aptX Lossless could do is 24bit 48kHz (because of 2M link restriction). aptX Lossless have different version, one for A2DP, one for LEA. 24bit 96kHz lossless is 4.6Mbps, even if QCOM...

I think you got mistaken. aptx lossless first gen bitrate is 1.2Mbps (16bit 44.1kHz lossless compression), the next rev are 1.4Mbps (16bit 48khz). AFAIK no product have this yet and not publicly released by qcom.

Also i heard aptx lossless will have yet another revision in the future, now support 48kHz instead of 44.1kHz as of now.

Money is not the reason why Samsung not adopt aptX HD/Adaptive. Like the guy above said, its just pure competition. They want to push their audio products as top choice for Galaxy buyers. Samsung got (bought) every bell and whistles QCOM offered. Then they just dont use it and deploy their own...

I dont know as Qualcomm havent shared more details about that, they just said that XPAN-supported router is required (of course must be qcom powered). Something about the router also need to aware about XPAN links between phone and audio products....

XPAN also requires XPAN-supported Wifi 7 router (also using qcom chip) too.

Here is my UTWS5 firmware archive for anyone interested (v1.30 -> v1.74): https://drive.google.com/drive/folders/1vCw2B41R0OYq9PXRZwHCbFnM1e_OMpyB?usp=sharing

Hello @FiiO does the UTWS5 support aptX Voice 32kHz for calling? I dont see any solid confirmation that it does support it. Thank you in advance.

I just tested LDAC connection with my PC (using Qualcomm FastConnect 6900 wifi+BT card, sadly no QHS). 909/990kbps working fine, altho the first 10 secs after connected and playing a song will output noise, then the earhook seems to stabilize itself (radio recalibration?) and no issue after...

Audeze Maxwell supports LC3Plus, altho I never tried it

https://www.androidauthority.com/qualcomm-announces-ultra-low-latency-chipset-3335410/ We should see USB dongle with QCC3086 any time soon:)

I think with LHDC the issue is in the codec implementation. Because I tested LDAC at 990kbps and it works, both non Snapdragon Sound and certified phones. Maybe QCC5141 can do high bitrate without QHS but very unstable.
