Audio Dropouts with New (2018) Mac Mini [Solved -- Time Machine]

I just increased the software buffer one notch and also changed the hardware buffering to MAX.   I still heard a little blip......

THere's also an "integer" option which I didn't understand

Dennis:

What I'm about to say is mostly my opinion backed up by my own experiences with this.  JRiver staff might disagree.  It's my opinion.

If your iMac has a spinning disk drive and not an SSD, I believe that this is the real source of the problem.  JRiver was never able to duplicate my problem and I believe all of their test machines have SSDs.  My newer iMac (2014) has an SSD and I've never heard any kind of interruption in MC's playback on that Mac.

About the software buffering:  Try at least 500 mS.  500 mostly removed the problem for me.  I believe 750 made it totally go away... it's been a long time since I tested it.

Good luck.

We have two Mac's and I don't think either has an SSD.

Edit: I was wrong.  They both have SSD's.

And if a spinning disk was the cause of the problem, that would be a hardware or OS problem.  We just use the OS to read from a disk.

Dennis in FL:
I have a 2014 iMac with a 3TB fusion drive.   The fusion drive has (I think) a 128GB SSD section but I have no idea which files end up in the SSD - the idea is the SSD gets the most frequent files in use.   

I also have a Macbook Pro with a pure SSD drive but I have yet to try MD25 on it.   Maybe today.

In the mean time, I'll try a little more on the software buffer.

But since I'm reading the entire album into memory.....doesn't that eliminate the disk access speed issues?


blgentry:
I have some weird theories on why this might be true, but I think simply having a spinning disk drive that is fairly full (over 60%) can cause this to happen.  I might be wrong; this is based on my system and the reports of others.  I don't have any data on Fusion drives so who knows. This is mostly educated guessing anyway as opposed to any kind of real scientific conclusion.

The software buffer should really help.  500mS should remove most of your dropouts.  750 *should* eliminate them entirely.  I would bet your system with the SSD will have none.  I'll be interested to hear your results.

Good luck!

Brian.
