Dear friend,

Could the BTR1K work fine in Windows computer instead? And you are also using Ubuntu 18.04?

Best regards

Dear fiio, i also got the same problem but my device is BTR3, if you ask can it run in windows , yes it can. plugged in and sound automatically directed then get audio out. But on linux the device itself detected Fiio BTR3 (IEC958), the sound directed but BTR3 dont give audio out. It doesn't matter on alsa or pulseaudio.

Am i must place this on fiio btr3 thread? or can we just discuss here?
thanks

I think they may be having experts watching each thread, so posting in the BTR3 thread may help get the quickest answer.

The problem you're having seems to be related to Ubuntu, any chance an Ubuntu dev can help? Other USB DACs work well?

ok after playing around a bit, I got it working. I need to make 'force' pulse audio output 32bit sample format by using float32be in /etc/pulse/daemon.conf. I'm looking around for someone who can confirm this and playing around with sample format. thanks.

edit1 : solved by specified s16le or s32le, just specify something in pulseaudio daemon.conf, leave it auto 'commented' guaranted no audio out.

Great! It finally works. I had to specify also default sampling rate as 48k, instead of 44.1k. So in my /etc/pulseaudio/daemon.conf are these lines:

default-sample-format = s16le
default-sample-rate = 48000
alternate-sample-rate = 44100
default-sample-channels = 2
default-channel-map = front-left,front-right

And you must select the Digital Output (S/PDIF) FiiO BTR1K in PulseAudio's control panel, not the Ananlog Output FiiO BTR1K (why is it there?).

Thanks, works also for me!

I have recently purchased the btr1k, and i'm having some issues with it,
When i connect it to an avantree priva 11a transmitter, the avantree indicates that is transmitting aptx ll, but the btr1k indicates that it receiving only sbc, and the sound is very distorted.
I also have a mpow transmitter/receiver that supports aptx ll, and that is the same.
It works fine with my phone and tablet.
Anyone out there having the same problem ?, and any solution.

I have exactly the same problem with my Avantree Priva III (except for the distortion). It works fine with the BTR3 but the BTR1K does not. It might be the chipset (i read somewhere on amazon that avantree recommends csr shipset which is the one in the btr3), although i don't know why the excellent qualcomm chipset in the btr1k wouldn't be supported. It's also annoying i cannot check the settings with the fiio app. Disappointing fiio has not responded to your question here (i sent them (and avantree) the issue, let's see how that works out). Slightly off topic: the fiio app is disappointing : partly invisible ui on my iPhone se, connecting archaic, settings not saved and still no eq.

Dear friend,

Please send email to support@fiio.com about that.

BTR1 or BTR1K ?

id like to buy one of the two devices for my brand new smartphone (SONY xperia XA1 plus). The main purpose is to listen to music/music playback.

music quality: wav, flac, mp3 320kb/s.
headphones: beyerdynamic custom one pro plus with 16 Ohms and Philips Fidelio S2 in-ear with 22 ohms.

I have three questions:

Both devices are equiped with the noise cancellation feature (qualcomm cVc noise Cancellation). I'd like to
disable the noise cancellation (mainly) for music playback because it (probably) will affect the quality of the playback.

*) does the noise cancellation feature also affects the playback of music?

*) is it possible to completely turn off/disable the qualcomm cVc noise cancellation (for calls and for music playback) ?

*) My smartphone has only Bluetooth 4.2. Is it fully compatible with the Bluetooth 5.0 version of the BTR1K?

thx a lot !
greets from germany!

Dear friend,

The cVc noise Cancellation is only available in calling mode.
Theoretically, the Bluetooth 5.0 device can be compatible with Bluetooth 4.2 device.

If on a scale of 10, BTR1K is 9.5, where would my Mpow with csr8675 rank?
My Mpow has the same bluetooth chip as the btr3, but lacks the high end dac and amp design.
But on my efficient headphones Mpow works quite good.

Am I the only one that would like the power button functionality to be swapped with the side button currently used for play/pause?

 

[The Socialist Nerd]

I just ordered this and will see how this goes...

Hope it could meet your need.

How do we differentiate the previous btr1k with blue-tooth 4.2 to the newer version with blue-tooth 5.0?

Is there a different code number or other way to know which btr1k is being purchased?

I am going to test this Bluetooth DAC with my HIFIMAN 4XX headphones against my Mobius. I will be reporting back here for sure.
