Looks like it's a duplicate of already expired bug 1850502. Since I'm able to reproduce this by playing YouTube video streaming, I'm to set that bug as a duplicate of this instead.

[You-Sheng Yang (vicamo)]

Can still reproduce with current v5.8 mainline build with linux-firmware 1.189.

[Shyam Jos (shyamjos)]

@vicamo I reported this bug 10 months ago, and I am still having this issue in 5.7.x kernel.

Are you able to reproduce this issue with 5Ghz band wifi connection? ( connect Bluetooth speaker and play a YouTube video) ?

Are you able to reproduce this issue with 2Ghz(20Mhz bandwidth) band wifi connection ? ( connect Bluetooth speaker and play a YouTube video) ?

[Shyam Jos (shyamjos)]

I am suspecting BT interference with 2Ghz (40mhz bandwidth ) connection.

Right now I am testing this issue with 5Ghz and 2Ghz 20mhz bandwidth wireless connections. Will report my findings here soon.

@Shyam, yes, I was on 5G WLAN, trying 2.4G. You might want to reply to that lkml thread as this can still be reproduced with mainline kernel.

[You-Sheng Yang (vicamo)]

Also reproducible with a 2.4G WLAN.
