[SOLVED] Sound jumping with bluetooth speakers when using youtube

Hi friends,
I noticed that when playing sounds from youtube in firefox or spotify as an app from aur then the sounds cuts off every now and then for half a second.
I tried different bluetooth speakers, same problem.
I tried playing youtube and spotify from the laptop's native output and the sound is perfect.
I tried playing music from VLC and the sound is perfect.

Could you please let me know what would be interesting to look at to find out what's wrong?

Cheers,

Re: [SOLVED] Sound jumping with bluetooth speakers when using youtube

Likely sampling differences, what's your output for

pacmd list-sinks
pacmd list-sink-inputs

for the properly and not properly working situation.

Sorry for the late reply. Things were working fine for a couple of days. And now their are bad again. I didn't change anything in the packages or configs in between.

pacmd list-sinks

Re: [SOLVED] Sound jumping with bluetooth speakers when using youtube

Please wrap all of that in [ code ] rather than [ quote ] tags.

Other than that looks somewhat alright. You could also be running into wifi interference here, how are you connected to the internet? Via wlan? on the same chip as bluetooth? If you can switch your wifi network to exclusive 5GHz band and/or check whether your wifi module has some bluetooth coex option.

Re: [SOLVED] Sound jumping with bluetooth speakers when using youtube

I ve got a laptop Dell XPS 15 9530. I m connected to the internet vie wlan. I'm not sure how to check if the wifi is on the same chip as the bluetooth.

Re: [SOLVED] Sound jumping with bluetooth speakers when using youtube

Hi @V1del

I've tried the Bluetooth coexistence when it was giving me grief and it worked normally straight away.
After a few days of testing it seems to be holding. I think this can be marked as solved.

Thank you so much for your help. This community is of the highest quality.
