Audio is half speed after disconnect from bluetooth speakers on Zorin OS Lite

Hi,

I'm a new user. Overall, Zorin OS Lite works wonderfully on my Asus T100 laptop/hybrid combo, which is infamous for being finicky about Linux installs. Zorin Lite effectively revived the device, which was barely functioning on Win 10 and quickly ran out of disk space, so overall I'm pleased with the results of switching over!

The only hiccup I'm encountering lately is that the audio is fine on my built in speaker and fine on the bluetooth, but after I disconnect from bluetooth (for example, if I want to charge the BT speaker), audio from local files and streaming (ex Youtube, radio etc) slows down to about half speed. The only way to clear it is reconnect to bluetooth (not ideal as I sometimes WANT to use the built in speaker) or reboot altogether.

Anyone encounter this before and, if so, any idea what might be going on here? Thanks in advance and let me know if I can provide any further details!

Welcome to the forum! Glad you're enjoying the experience so far.

As for the bluetooth issue, when you say half speed, does it actually make a 3 minute song last for 6 minutes instead? Or does it just shift the octave of the audio coming out so that it's much lower than intended? I can't say I've run into a situation where the audio will get literally slowed down versus just pitch shifted.

Thanks for your reply! The pitch goes down at least an octave and the playback speed definitely seems slower than typical. To be clear, this only happens from the built in speaker AFTER disconnecting from a bluetooth speaker. I can plug the speaker in directly with a 3.5 mm cable and avoid this whole situation, I guess, but I just wanted to check and see if there might be an obvious fix or anything.

Ok, if you're able to do some testing, if you try making the same issue happen, and when the weird sounding audio starts, if you want to try in the terminal

pulseaudio -k

Does that seem to fix the issue (at least temporarily) for you?

Thank you! I'll try that next time and report back. And yes, I talked myself into using the workaround for the time being. Appreciate it!

Let us know how you make out! The issue with audio is there's so many layers it could go down, that it's basically about going through the checklist of everything and then figuring out that it's because the sun is out on a tuesday, when it should've been cloudy haha.

So true and well said! Happy to report that I was able to fix the issue. Here are the steps that worked for me (source: Comprehensive Sound Problem Solutions Guide). This essentially flushes the audio config/related packages and reinstalls fresh, at least from my understanding:

(1) Remove these packages:
sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils
(2) Reinstall those same packages:
sudo apt-get install linux-sound-base alsa-base alsa-utils
(3) Reboot

All's well again the audio sounds fine on both the built in speaker and bluetooth speaker. Posting here in case it helps someone else out. I'll write again if anything changes too. Thanks a lot for the support!
