Hi,
Playback is constantly skipping, making noises, cracks. Sorry, I can't find the right word, english is not my primary language.
When it happens, I need to restart the mac and try again. Eventually it'll normalize.
I used to be able to use JRiver on a regular basis, but i'm having these problem since 201 I think.
I used to have Audio on Hardware default, but I switched to Maximum recently. I don't know if this is part of the problem because when I go back to hardware, I still have the problem. I remember even restarting the computer with the default option. same problem.
Sometimes JRiver hangs and I have to force quit although after I wrote that first post, I couldn't reproduce this behavior.
My interface is Apogee Duet 2.
Matt:
Please use 'Hardware default' for the buffer size. Then reboot and test a single sample rate.
Does that work, or do you still have problems?
After that test, we'll slowly add more complexity.

This guy explained the trouble better than I could ever explain. Its the exact same thing, but with the mac version.
--- Quote ---As some of you know from my recent posts, I just started using JRiver for my music player. I am having an issue with skipping during playback and I cannot seem to figure it out. There does not appear to be a pattern with the files as it occurs with 16/44 as well as higher resolution. All files are FLAC and they reside on an OWC external drive connected via eSATA to a Windows 7 laptop. The laptop is output via USB to a Berkeley Alpha USB. MC is set to output mode WASAPI and the following are checked:
-Open device for exclusive access
-Flush device buffers on startup
-Flush device buffers on pause (recent change to see if it would correct skipping which it did not)
I tried increasing the buffer all the way and it did not correct it. Prebuffering is set to 6 seconds.
I need to start another song and sometimes exit the player and restart it in order for it to stop skipping. It occurs randomly, sometimes a couple times in a 10 minute period and sometimes not for hours.
I'm a bit baffled. Anyone experience this or have any suggestions?

I tried Hardware default and the other two options without success.
The other two options I tried was memory playback and exclusive access.
Its not a constant stuttering, its every now and then. thats why I think its will be more challenging to get to the cause of the issue.
It could be a conflict of software maybe? The duet drivers maybe? I dont know.
Matt:
Sorry, but I'm not sure exactly what's happening. That means we'll have to try some things to try to figure it out.
After switching Output device settings to 'Hardware default', please reboot the computer. Some hardware doesn't reset until that. Does that help?
How fast is your machine? Post the JRMark score from MC > Help > Benchmark.
Could you try playing files from a local drive?
Thanks.
rinoatomy:
Hi, alright.
I'm gonna try to reboot the computer and report back soon. (or later).
Fast? should be sufficient to playback audio, I think.
My files are all on my local drive, not external.
