If you get the same result as me, there will be no sound coming out because of the channel being reserved as an input with the default sound profile for Bluetooth devices with microphone(s).

You can reproduce the channel behavior I mentioned by changing the channel of the DAC's at the end (both at the same time) from 1 to 2 and try to play again.

You will encounter reliably what I have encountered and other have also mentioned with the crappy sound quality and dropping.

Then configure the BT device with iOS settings app, then come back to Audulus and try to play again.

Play a bit through the default speakers or a wired headset and note the richness of the sound (I used the Audulus official live stream on youtube as a framework for setting up the patch, and made a few modifications).

You can test this behavior and reproduce by downloading, opening the patch, and doing the following.

I have also attached a patch I used to qualify/document what I have stated above. I have attached screenshots documenting this behavior on my Mac. Upon changing the microphone to the device internal, the load is taken off of the BT device, a better quality codec is selected (AAC in my case), the headphones switch to stereo mode as both channels can now be utilized, and the sound no longer clips, blips, crackles, pops or drops.

I had the same issue with my BT headphones (all of them) with my Mac until I manually switched the microphone on the headphones off in the Sound Preferences > Input section, by choosing Internal Microphone. It appears that because Audulus is capable of taking in sound, when BT is configured and a microphone is available on the headset/speaker, instead of using stereo sound (channels 1 & 2) and AAC or APT-X codec, Audulus and iOS set the headset up as a 2-way communication device, which defaults to using the headset microphone and has audio streaming to you in mono on channel 1, with channel 2 being reserved as an input (even if it is not being used, see attached patch) and the codec set to SCO or SBC.

The issue seems to be with the codec and profile that is chosen by the Audulus application asking the system what to do or the system asking Audulus what it wants. I am going out on a limb here, but I’m guessing that your Philips BT headset doesn’t have a microphone? Either that or the patch wasn’t producing enough information bits to overload the single channel’s buffer in the crappy default profile that is chosen when the headphones are in use with Audulus on Mac and iOS. The common denominator with all of the bluetooth issues I am having is the fact that they all have a microphone and support for phone calls. Hey guys! I have done some extensive (some might even call it obsessive) research on this subject with all of my bluetooth headsets since discovering this issue a couple weeks ago. Just to confuse matters, I dragged out my Philips bluetooth headphones this afternoon, and they work fine with Audulus.
