I have some albums stuttering.  They are CDs that were ripped.  I tried re-ripping a couple even down to 2x rate... the originals were .wav files now I am using FLAC. The CDs still stutter. I have others that don't... I have a bunch of vinyl that I ripped 24/96 with Vinyl Studio and so far they seem fine.  I use secure rip and check the logs.  I have exclusions in Trend Micro AV and added the exclusion to Windows defender.... no go...
Focusrite Scarlett 2i2 series 2 DAC, ASIO driver. Windows 10 16 Gig ram.

HELP....

I assume you mean stuttering during playback.  Have you tried playing back the files in question in different audio players, just to see if it happens in all players?  I'm wondering if the error is in the file or in the playback program.

Also if you use dbPoweramp to rip (I think JRiver has the same feature) your rip checksum is validated against a database of everyone else's rips, so no possibility of an undetected error.  Depending on what program you're using to rip, "Secure" might just mean an assurance from your CD drive that it thinks the data is correct, nothing more.

When I have had a small number of discs that were problematic to rip, I was able to rip them successfully in a different drive.  Do you have the option to try a different drive, especially a different brand?  I have two PCs in my house, and I always make sure their optical drives are from different manufacturers for just that reason - a second opinion.

The sound is actually more like a click... not exactly like the pops and clicks from vinyl but close enough.

The problem CDs that were ripped were all ripped by MC in "secure" mode and most of the library was ripped with my last PC.  It still runs but used in my workshop now.
So I tried re-ripping on my new PC and no difference.
I just downloaded VLC player and the the problem CD plays perfectly through VLC!
Both the PC that originally ripped the CD and the current PC are Dell I7 computers with a lot of RAM.
So the issue is a playback issue with MC. I discovered that I had not removed MC23 from my PC so I tried it there and had the same issue.

Two guesses:

Try rebooting the PC. I've had MC (in a client server setup) do something similar. A reboot fixed it so worth a try.

DSP settings causing clipping?

From what you've said it doesn't look like it's the source files. MC doesn't do that normally so it's either the MC settings or maybe the PC needs a reboot. (Assuming the files are stored and played locally)

Just switched to wasapi instead of ASIO and the problem went away... Why would MC not play nice with the Focusrite ASIO driver?   I have the latest driver.

[Awesome Donkey]

Open the ASIO driver's control panel, it sounds like the ASIO latency is too low.

[Jeff W.]

All that is provided in the ASIO panel is: Sample rate  44.1 and Buffer which is set to the max of 1024 by default
Now using the wasapi driver it starts to "garble" the audio after listening for a while. If I open and close MC24 it clears it for a while.

[swiv3d]

did you uninstall all previous versions of the driver before installing the newest focusrite drivers because that is apparently a source of a lot of problems.

[Jeff W.]

I just did the uninstall-reboot-reinstall to make sure!  NO change.

I did stumble on something that may lead to the resolution if someone can explain what goes on under the hood!

I looked into the settings under DSP studio. I DO NOT have any of it enabled... nothing at all. BUT at the bottom seems to be a status line indicating Source data and Internal data settings!
So on things that have the glitching issue the Source is 44.1 Khz, 16 bit 2ch and Internal is 44.1Khz 64Kbit 2ch
On albums that play fine: Source is 96Khz 24 bit 2 Ch. Internal is 96Khz 64 bit 2 ch.
So internal transcoding?

[swiv3d]

If you have no settings in dsp studio it should not be having any effect, Have you tried going to the asio set up panel, there is usually a button to enter the driver set up.

[Jeff W.]

Yep very plain Focusrite driver screen... two things:
Sample rate: 44.1K
Buffer: 1024K
If i mess with the buffer it seems that Media center always puts it back to 1024K

[swiv3d]

Just have to hope a focusrite user sees this thread then! Sorry I couldn't be of more assistance. You might changet the title to ask for focusrite help!

[Hendrik]

Changing the buffer works for me. Note that its not MC saving those values, but the driver itself. Make sure nothing is playing at the time however.
Alternatively, you can also open the driver control panel independently of MC, at least on my Focusrite 18i20 thats possible.

[Jeff W.]

Right I have opened it independent of MC... stays where I set it till I open MC...

[Jeff W.]

Renamed it... will see if that shakes something out

[Jeff W.]

Issue resolved.
It was the Focusrite Scarlet 2I2 driver. Focusrite had me remove their driver and run with the generic Windows driver.
