View Full Version : Dropouts on Mac

I have just purchased a wireless Squeezebox3 to go with my Mac and PC.
I am using a Netgear DG834PN modem/ router.I have successfully created a wireless network on the Squeezebox, and I can play back songs perfectly from my Windows PC.
The problems start with the Mac.
I experience HUGE dropouts when playing back music on the wireless network.
Internet radio is fine, and when I create a wired network, playback from the Mac is fine.
SlimServer seems to successfully scan my iTunes library on the Mac.
I was hoping to purchase multiple Squeezeboxes to install around my home, but unless I resolve this issue, I may have to consider a Plan B.

Can anyone help or advise ?

Thanks.

There were some changes today to help out with iTunes.

Download the 6.2.2 nightly from http://slimdevices.com/dev_nightly.html after
2am PDT tonight. Also consider increasing the iTunes rescan interval to
either very high, or to 0.

Well, to diagnose I would have a look at what Activity Monitor says,
and also at SlimServer's Network Health.

From the little info you give, one can't say if you are having
network dropouts or if something is frequently using 100% CPU.

Same problem here with an SD2. I only have a Mac so I cannot compare to the Windows platform. I set up the slimdevice in couple minutes, use iTunes for the music. My router is the Dlink dgl-4300.
From time to time the music breaks and SD2 is not very responsive, it also takes time for the SD2 to respond to the remote control. When I go on the Mac it takes forever to access slimserver.
After about 10 minutes it gets back to normal.
This happens reading directly AAC files on the Mac or getting a local stream I create using Nicecast.
I downloaded and installed this morning Slimserver 6.2.2 and now the SD2 got stuck couple times on the message: Cannot connect to Slimserver.....
After 30 minutes I unplugged the SD2. The funny thing is that when it got stuck I could access the Slimserver on the Mac and it looked like all was working fine but the actual SD2 was still non responsive to anything.
I am losing patience here, I love the SD2 when it works but want it to work for hours without any problem.
Anything I should try or look for in the Slimserver Network health or anywhere else?

Hi Daniel,

Sorry, I don't mean to give so little information, I really do want to fix the problem.
If you can tell me which info you would like & explain to me how I go about getting that info for you,I'll gladly do it, no problem.
If you can help, I'd appreciate it.

Spookie.

Do you only experience drop outs on the wireless network?
If so and you are using 6.2 - try downloading the NetTest plugin [http://forums.slimdevices.com/showpost.php?p=66366&postcount=37]

This allows you to test the performance of your wireless link. If it does not show 100% at the rate at which you stream - e.g. 1000bps for flacs, then your problem is the network.

If this looks OK, turn on performance monitoring from the Server and Network Health page, queue up some tracks to play and leave it for a while. Then post here what the Server Response Time graph looks like.

I have problems with both wireless & over ethernet, but it's only with the Mac.
The Windows pc is fine, in fact it's perfect.
I'll try those tests now & get back to you.

Oh, I'm no expert, just a long-time user. And when I said "I", I
meant that you should do so and report back.

This forum is full of people who know a lot more than I do, and if
you can give enough information someone should be able to help.

I'm always in favour of giving as much information as possible. Which
Mac, which version of the OS, which version of SlimServer, which
router (you did give that information).

You said "huge" dropouts, and I assume you mean that they occur
frequently, not that each dropout is of long duration. Is there any
pattern in the dropouts? For instance, do they occur at regular
intervals? There are processes that may use up a lot of CPU
(refreshing the Web browser, rescanning the library, etc). Dan Sully
suggested one thing worth trying. Triode suggested something else,
which will help to check the network.

The other suggestion I made was to turn on Activity Monitor (it's in
the Utilities subfolder of of the Applications folder), perhaps order
the processes by CPU usage, and watch to see if any process is
repeatedly showing up with very high usage.

Wired is inherently more stable than wireless, and it is possible
that some SlimServer related issues are always occurring but only
show up with a wireless connection. Oh, I've just seen your later
post. Originally you said it was fine on a wired network, so I
assumed a wireless issue, but your new message says there are
problems even running wired, which suggests a Mac issue.

You said "I can play back songs perfectly from my Windows PC." I'm
not entirely clear if your music is on the Mac, and whether you were
playing music on the PC (from the Mac), or whether you were running
the SB with a PC SlimServer.

Network issues are common, and can be caused by what is happening in
a nearby building or apartment quite easily.

I have an SB2 (previously an SB1) and as just one example of what can
happen I often lost sound when the microwave was on. But I changed my
wireless channel and have had no problems since then.

On my side, I just had lots of dropouts and checked Activity Monitor, CPU usage was to the max. I was streaming music to the SB2 using Nicecast. Once I selected to play directly a song and stopped Nicecast things went fine.
Since I experienced dropouts without Nicecast before I will keep the test running. I also set iTunes library to be reloaded every 10 hours. It was by default every hour and that could match the interval when for 10 minutes I had the dropouts.
Thanks for all the help on this forum.
