I'm a new Synology nas user and very happy of my DS411slim. Like most users I bought my DS mainly for the network storage purpose but I can say I am very surprised by all the stuff that small box is offering
Until yesterday, I played my mp3 music files stored on the nas from my computer through the web browser in streaming mode. This works very well. I have no issue to report.
But yesterday, I received my new V-DACII (Musical Fidelity). I finally bought it even if I was not sure of its fully compatibility with the DS411slim. The V-DAC (version I) is known to be working with nas synology DS410 (source http://forum.synology.com/wiki/index.ph ... B_Speakers
). The main difference between the V-DAC and V-DACII, is the new asynchronous USB port on the V-DACII (equal to V-LINK + V-DAC).
My happiness was very short, because after few minutes of listening, I got the problem you described very well... some couples interruptions in the sound every 2 at 3 minutes. Then I realised I got the exactly same problem one week ago with a very cheaper usb sound adapter included with a more cheaper audio headset...
Last night I tested almost everything to avoid this problem, without success... so I wrote to synology support for help but I don't have an answer for now.
But I currently have a good new, for I am writing this post (and believe me it's taking a very longtime because of my laggy english
) I am listening music on my nas in USB mode without any interruption since now two hours.
I am still not truely sure but I am guessing the issue could come from the volume control button in the web audio station or even with the volume control in DS audio for Android. Both start with volume control button at extrem left. If I do nothing, sound is muted, if I put it at extrem right, audio is unmute (so just normally working). But after few secondes, without reason, the button goes back to initial position at extrem left... the sound is not impacted by this changement anyway for now. When it does happen try don't moving it anymore. I guess by "playing" with the volume control button the issue occurs. It's like if the sound was muted for a couple of half second because of a buggy control volume.
Hope this will help you to resolve your problem
