It is an Asus Xonar DGX and has a toslink connector. The soundcard works fine in my machine, but I am still getting a stuttering/dropout while playing music under MC. It's not really subtle. It's pretty noticable. I mean I can hear a wobble every 10/20 secs or so. So it seems it's a MC/Linux thing still. I'm on the latest MC 24.0.74 and running the supported OS. It's an older motherboard but should be more than up to the task. It's an Asus P5B which has a quad core Intel processor and an Nvidia GTX950 video card and 8G memory. Everything else seems to run perfectly on this machine. I'm going digital direct into my Denon receiver.
I also just tested another Windows machine that I use for backup mainly. Running the latest Windows version of MC (24.0.74) off the onboard toslink to the same receiver, same input, it's perfectly fine.
The thread priority thing sure sounded promising and seemed like it would have explained the symptoms I am seeing. So I am at a loss now. It seems to be something tied to my hardware (and not the soundcard/chip) and Linux/MC.
Thanks for the suggestions so far. Much appreciated.

Not sure what you are seeing there. We've been running on Raspberry pi's without dropouts and they are orders of magnitude slower than what you are using.
The Audio settings in MC should be set to a hardware device (hw or hdmi).
You can tune the buffer setting in the Audio device settings.
The defaults are 500000, and 100000 microsecs.
You should be easily able to drop those each by a factor of 10, even 100 to reduce latency.
If you get dropouts as you reduce those there is something wrong with your system, either in the input chain (are the files on disk, on a NAS, etc?) or something really broken in your ALSA config or hardware.

Thanks for all the advice. I decided there must be some sort of card conflict in this computer. So I yanked out one of the cards, turned out to be a USB 3 card. That was the problem. I am back to the motherboard coax digital connection and it's playing back fine now.
Speaking of the Raspberry, I did setup a Raspberry MC with JRiver preloaded sd card. It plays back fine. It's just that I like theater view and the Raspberry is a no go on that as we discussed in another thread. This computer does all that just fine.

Well done finding the cause!
