I am trying to stream files from my pc upstairs to my downstairs Revo. I have recently installed an SSD on the upstairs PC (along with a fresh OS) I have also added a separate gigabit switch to the network instead of just going through the ADSL modem.

For some reason, now when I play files every now and again there is a half second loss of sound (the picture is fine). I am using VLC on the Revo and Homegroup to share.

The setup used to work well before but now I have effectively changed 3 things at once I am going to have trouble isolating the cause.

Has anyone dealt with a problem like this before? The problem appears random and is very hard to recreate.
 
Swapping back from the switch to the modem should be easy enough. What exactly is the network topography?

If you didn't format the old drive for a new use, you could swap that back in with the old OS install.
 
I have a wired network all going into a panel. The panel then connects to the switch and the switch to the router. Previously the panel connected straight to the router.

The old drive was formatted so no luck with that. I am going to try mpc-hc tonight to see if that resolves things. I was told that vlc was not so great.

Previously data and the Os were on one physical drive. Now the Os is on the SSD and the data remained on the mechanical HDD. I wonder if this has anything to do with it.

It is most infuriating.
 
What is the Revo plugging in to, an avr ? are you using spdif or hdmi.

I would plug some headphones in to the revo and see if the sound stutter is still there.

The only time i have had sound stutter as you describe is if i try and send a two channel pcm over spdif passthrough without encoding it, to an AVR. Then the sound glitches every 10-15 seconds.

But as the revo has not changed and you are just running through the network that would point towards a network bandwidth issue. But it sounds like an odd problem. What about if you copy files directly to the revo and try and play them, do you have the same problem. copy some files with software that you can view the transfer rate and see if it is not up to speed.
 
I'll do some diggin on this.

I remember I also recently changed the memory usage to 512mb for the ion in the bios.

Gah I should have learned not to fiddle with things that were not broken!
 
The development from last night is that
A) most of the stutters came later in the 1hour file
B) I can reproduce them- if I rewind they happen again. The source file is fine as it does not stutter on the pc that the file is stored on.
 
A friend of mine had a similar situation streaming to a PS3, we found turning off the HDD sleep in advanced power settings cured his problem.

Give that a try, alternatively, as you have also changed your switch, run a continuous ping test to check for drop outs.

I was getting the exact same problem on my FreeNAS box. As khrall and his friend discovered it seemed to be down to the acoustic / sleep settings on the hard drive. Removing these from the config seemed to sort the problem.

Hi guys- can you confirm that this is for the sending PC or the receiving PC?

For me it was on the server - so sending PC.

/edit

Don't know whether this is at all relevant it's a 2TB Samsung drive 203WI (Not sure on the model number but that looks right)
