Title: Rebuffering
Post by: ronfint on October 14, 2013, 06:27:35 am

With MC19 and 192/24 files of digitized LPs, about once per album there is a 5-10 second stop for rebuffering. I have never experienced this in MC18. I've played a bit with the buffering options, but this doesn't seem to help.

Thanks in advance for any help you can provide.

In Tools / Options / Audio / Settings, do you have "Play files from memory.." checked?

Yes -- play from memory is checked.

Are these long duration tracks read from a NAS drive?   Since Media Center reads the entire track into memory prior to playback, I wonder if the disk might spin down during playback of a long track and then take a bit to spin back up for the next track?

Yes, they are long tracks, but curiously, the rebuffering usually takes place in the middle of a track. The drive is a 3TB WD external drive, not a NAS.

I don't think we buffer more than one Gigabyte of data, how big are the tracks?

Thanks, John. I'm not talking about tracks that are that big. Yesterday, I had this occur once on a track that was about 600MB.

Out of curiosity is your external drive set to sleep or hibernate after a certain period of inactivity?

I don't think so --- but I don't even know how to check that.

Well, two answers, it can be configured via your Mac in System Preferences under Energy Saver (see attached). The second is some external drives have a firmware controlled sleep mechanism. In the instance of WD, I believe they sometimes ship with WD Drive Utilities or WD SmartWare (depending on the type of WD drive, i.e. My Book Essential) which you could use to disable the sleep timer.

That being said, perhaps it is not a case of the drive itself going to sleep. Just exploring all alternatives.

Thanks --- I just unchecked "Put hard disks to sleep ..."

Did it help?

John, thanks -- yes this seems to have helped. I listened to the same album that stalled this weekend. Tonight there was no problem.

This is great to hear, though I don't have a WD drive myself I did read up upon this potential "issue" on some of the forums. Call me a happy MC user!
