More and more often since macOS Catalina 10.15.4 Supplemental Update (Install Date 4/8/20) I must restart the computer to get the sound back. Is this a common problem that needs to be fixed or is there a possible remedy? Thank you.
MacBook Pro 15”, macOS 10.15
Hard to say.
A Troubleshooting Procedure that may Fix Problems with macOS El Capitan or Later
You should try each, one at a time, then test to see if the problem is fixed before going on to the next.
Be sure to backup your files before proceeding if possible.
1. Select Disk Utility from the Utility Menu and click on the Continue button.
2. When Disk Utility loads select the drive (out-dented entry) from the Device list.
3. Click on the Erase button in Disk Utility's toolbar. A panel will drop down.
4. Set the Format type to APFS (for SSDs only) or Mac OS Extended (Journaled.)
5. Click on the Apply button, then wait for the Done button to activate and click on it.
6. Quit Disk Utility and return to the Utility Menu.
7. Select Install OS X and click on the Continue button.

Test in safe mode to see if the problem persists, then restart normally. Use safe mode to isolate issues with your Mac and 1. Playing Safe - what does Safe mode do?
I am still getting sound at all times so I think, luckily, it was an easy fix using safe boot. Thanks again so much.
Thank you. I tried disconnecting an external hard drive, rebooting the sound controller, and testing in safe boot. It seems that safe boot has corrected the problem so far. I will have to wait and see if that is the solution.

Yes. What I was unclear about in my original post is that although I definitely had no sound in Apple Music I don't remember about Sound Effects. I use a sound enhancer and a loudness meter which complicate things for me because these involve more settings and more possible software to reinstall, etc.
l just noticed that the sound enhancer's Forum has this post from yesterday which may somehow be part of the problem because it is exactly what I experienced.
"Since upgrading to Catalina 10.15.4 I keep having instances where I lose sound altogether whilst [sound enhancer] is active. Sound can be working fine then later when I return to my Mac desktop there’s no sound. It seems the only way to get it back is to reinstall [sound enhancer] over the existing app."
I hope that I keep getting sound because I expect it from a new MacBook Pro 2019.
If core audio is crashing, then the fault is probably with the software that is using it. Which wound enhancer are you using? If you are finding that the crash of core audio always happens when the enhancer is run, then you should report that to the developer along with a copy of the crash report.
To me, crash reports are usually meaningless. They are intended for engineers to use with debugging hardware and software, so they can find an fix problems. It's all Greek to me.

Bongiovi DPS.
I did that yesterday.
Thank you.
I've use that before and had no problems with it. Are you using the most recent version? Have you reported the problem to the developers? If you uninstall it, does the problem cease? What other third-party add-ons are you running along with it, especially other audio add-ons?
The developer has a forum with a post started in April 2020 addressing this problem that has affected a few users since macOS Catalina v.10.15.4 but there is no solution yet. A user thinks that something disables a necessary component of Bongiovi DPS and they will give DPS full disk access just as a wild guess.
I recently reinstalled DPS using fresh installation media found at their site.
About a week ago I emailed a support team member directly and, as I mentioned in my previous post, yesterday I reported my situation to the developer by opening a ticket and including a Console crash report I found with the Process Name: Bongiovi DPS.
I have been using this application since 2015 with no major problems that I can remember. Apple Music works fine if DPS is turned off.
I think that the only other third-party, audio, add-on I am running along with it would be Orban Loudness Meter ('which is designed to meter inputs and as such the speakers aren’t a source for metering. There are several third party applications available that allow internal audio routing that would let you make that route happen') so I need to select DPSReflector instead of MacBook Pro Speakers as the Output Device to see the meters react.
I used it from its first release and had a minor incompatibility problem. That was fixed in the next update. It worked well but I had problems with it when doing FaceTimes, so had to turn it off. Otherwise, it worked fine. I hooked up an external sound system, so I no longer needed it. I'm sure the developers will fix the problem. They seemed to be very responsive.

The problem may be with the sound enhancer. If it makes use of core audio, there is a possibility that core audio crashes which would explain your loss of audio.
i have problem getting online, youtube, my aol.mail,..... have to shut down and restart again and again. what is the cause
If core audio is crashing, is there a way to try and fix that? Also, would you like to see a Console crash report for the sound enhancer from today? Thank you.
No sound until I restart
