audiomacbook prosound-volume
When I'm working on my 2017 Macbook Pro with 10.14.6, the audio often stops working. I can hear only beep of Siri, nothing else, no Youtube sound, no Skype call sound, no zoom sound, etc.
In Sound output tab everything is correct, the issue is fixed only when I restart my laptop.
Any idea what's happening? This issue is driving me insane.
The best step to isolating your issue would be to collect some data about the bluetooth environment where you are using your mac. Radio waves come and go with other devices, new phones, degrading antennas and changes in bluetooth firmware.
The Bluetooth Explorer is the best tool I have found to troubleshoot bluetooth hardware and data. It's free as part of Xcode from the Mac App Store.
You can debug data issues, see the protocols that connected devices are using, and get to all manner of engineering data relating to bluetooth such as errors, relative signal strength indication (RSSI). It's hard to tell if this will help you, but it lets me know when a microwave or home phone was causing noise issues on several occasions when my hardware was otherwise working properly.
Without resorting to AirPort or other networked setups, your only option is probably to just use a 3.5mm jack from your headphone port, which would unfortunately only give you stereo audio.

Reset NVRAM or PRAM on your Mac
If your Mac has issues related to settings stored in NVRAM or PRAM, resetting it might help. Sound also comes under this section, so I strongly suggest you to try this as after reboot your MacBook is getting normal.
How to reset NVRAM
Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P, and R. You can release the keys after about 20 seconds, during which your Mac might appear to restart.
When your Mac finishes starting up, you might want to open System Preferences and adjust any settings that were reset, such as sound volume, display resolution, startup disk selection, or time zone.
