Airport Express – Streaming Audio Stops randomly using iTunes

Close ...
Noticed that iTunes tracks being streamed via an AEX would randomly stop and would need a pause/play toggle to resume playing. Not sure what is going on but looking around the forums it looks like streaming with iTunes has been decidedly dodgy in the last few versions. Given that unless the late departed Man has a problem with a feature on Apple gear then action may not always be forthcoming I decided that using another app to do the actual streaming may be worth a look. There seems to be a few quite good audio apps out there but I settled on using Airfoil for Mac.

This app is a commercial one but not too expensive (c. £20 or so) and seems to have fixed the issue of streaming not working properly. Airfoil allows the steering of audio to any named AEX and can be used to enable streaming with numerous apps. I tried VLC, Quicktime, Decibel, iTunes and a couple of others. The final setup is currently using a Synology NAS with the iTunes library for cataloguing, etc and the Airfoil handles the streams to a couple of speakers on the Line Out jack of the AEX. The upside for me is that I can now stream my World Radio widget output (which uses Quicktime on the Mac) via the AEX speakers as well.

Note: the trick with Airfoil is to run it prior to the desired app so it can grab the requisite audio ports.

Sony Vaio VPCEB3F4E Win 7 64bit – re-install OS as Factory

Close ...
It appears that recovery disks are not provided with these machines. When they are purchased the HDD has a hidden Recovery Partition that can be used to re-install the software and it is up to the user to generate their own recovery disks to be used if the HDD should ever fail and need replacement.

I was lucky as the HDD was OK in the unit I had.

From Windows I did –

Start > Programs > Vaio Care > Recovery + Restore > Recovery > Recover Computer

This proceeded to install the software to factory spec OK. I did notice that there were a huge number of updates which surprised me with Windows 7 – seemed as bad as XP which is a lot older!

With hindsight it would probably pay to install Win 7 SP1 immediately after the factory install and this may reduce the number of updates to do.

Upgrade MacBook (white – 2,1 late 2006 Core 2 Duo) from 10.4 to 10.6

Close ...
The MB suffered from an instant hardware failure of the HDD which appeared to be a known issue within Apple but unfortunately mine was out of the 3 year window so my recourse was to buy a new disk and load in the OS.

Couldn’t find the Tiger discs since moving house so decided to try upgrading to Snow Leopard using the MBP discs (grey – machine dependent, 2009 – 5,3).

Used the Firewire Target Disk Mode with the MBP.

1 Install new HDD into MB
2 Connect MB with MBP via Firewire cable
3 Set up Target Disk Mode (press T whilst starting the MB)
4 Disk Utility on MBP said ‘Disk not Accessible’
Proceed with partition and give disk a name.
Disk will be partitioned and on restart of MBP will appear on Desktop.
5 Install disk will allow Target Disk to be selected for install (takes c. 1 hr)
MBP restarted during install and rebooted on Target.
6 Install completed – shutdown both machines and disconnected Firewire cable
7 Started MB and got –
Setup Options (regions/lang/etc
Selected options but didn’t connect to internet to avoid Apple-ID stuff – that can be done later.
8 Restarted MB and install appeared OK.

Install bundled Apps.

1 Used Firewire Target Mode again – MBP booted to Target Drive and install allowed.
2 Install completed – restart
3 Power down and disconnect Firewire – MB booted OK.

A new password will have to be entered twice and will be blind ie: not echoed to screen.
Type reboot and hit return.

WD RAID shares not available from OSX & XP VM

Close ...

- p4localshare (shared folder on C: of P4xpsp3computer)
- p4raidshare (shared folder on USB attached RAID - WD My Book Mirror Edition)

In finder under Shared as P4xpsp3computer, click on server and finder displays shared folders OK. If p4localshare is double-clicked the folder opens OK
but if p4raidshare double-clicked fails, get message - The alias "p4raidshare" can't be opened because the original item can't be found.

If I tried accessing the share from the XP VM on Parallels I got messages like - "not enough storage space" and "not enough memory"

Thought it may be the 'alias bit set' problem that affects some folk but when trying Pathfinder to check it was no good.
Pathfinder needs to connect and mount the share in order to use the Get Info to see the Alias Bit setting but it couldn't even connect saying the server didn't
exist ( it did - I could ping it OK).
Console showed Path Finder error - An error occurred while trying to mount "smb://P4xpsp3computer"., err: Error -41

The short answer to the problem was that the IRPStackSize value on the XP server needed increasing - I initially set it to 18 (decimal) but no good so I tried 30 and
BINGO, all the sharing worked again!

As a background the IRPStackSize came up on a forum ( as a fix for similar problems so I looked further into it.

Found a KB article at MS - Antivirus software may cause Event ID 2011

As it transpired I had only a day or two earlier uninstalled AVG 2011 and installed Avast Personal and that was about when the sharing had been flakey.

Interestingly the Registry on the P4 had no entry for IRPStackSize so I created one and noted when set to a value of 18 I was getting Event Viewer messages -

'The server's configuration parameter "irpstacksize" is too small for the server to use a local device. Please increase the size of this parameter.'

Setting the value to 30 fixed the issue.

It appears that there were no Event Viewer messages before I created the IRPStackSize parameter so they must only appear if the Registry parameter is present.

Method: (assuming registry backup has been done in time honoured fashion)

Use regedit in START>Run

Path is -
HKEY_LOCAL_MACHINE\SYSTEMCurrentControlSet\ Services\lanmanserver\parameters

IRPStackSize didn't exist so right-click and do New>DWORD, change value to Decimal and enter number (max 50 for XP)
If it exists right-click and do Modify.

Reboot on completion.

Check above KB article for absolute Registry details.

Fuzzy fonts using Firefox on OSX 10.6

Close ...
The fonts appeared to be anti-aliased and not clear but with Camino the text was good.
Decided to check the about:config settings in both browsers and came across an option called gfx.use_text_smoothing_setting - Camino was set to True and FF was set to False. On changing the FF option to True I found my text rendered clean just like Camino but the fonts in the FF app itself (toolbars,etc) were rubbish however I’m more interested in the clarity of the web page fonts so I’ll live with the toolbars!

Airport Express co-existing with BTHH2

Close ...
Decided to extend the range of the home network.
Arrangement: BTHH 2 on ADSL line (wireless on ch 4 with WPA2) and AE connected to BTHH via ethernet ( wireless on ch 9 with WPA2). The BTHH2 has DHCP enabled (BT Vision) but all clients use static addressing.

Plugged in AE (ethernet not connected) and opened Airport Utility on OSX 10.6.8 (Snow Leopard). The AE was duly picked up by the utility and setup commenced -
Create a Wireless Network -basically the Macbook used the wireless settings from the existing connection so I allocated a different Wireless SSID to the AE and used the existing password, etc.
At some stage it gave an option to Join a LAN which I chose - specified static IP ( and used the BTHH IP ( as the DNS server. When the config was done the AE was restarted by the utility and the existing wireless connection to the MacBook dropped, the MacBook then connected to the new wireless but found no connectivity to the internet (correct since it was still not connected to the BTHH). The AE was taken and connected via ethernet to the BTHH2 and the Airport utility detected the completed connection. The utility then checked a couple of details and required a firmware update which was successful (took a wee while - 3 or 4 mins or so).

The Airport Utility is quite a nice wee piece of software and gives options for various types of network configuration (joining existing wireless, extending existing wireless, etc).

I used - Create Wireless Network (on the AE)
- Join a LAN ( static IP for BTHH2 LAN )

The BTHH2 WLAN appears to co-exist beside the AE WLAN OK.
Initial indications show the AE signal strength to be a bit better than the BTHH but not massively so.

Upgrade of Aprelium Abyss X1 server breaks console

Close ...
Just upgraded my version 2.6 Abyss web server to version 2.7 and when a Show Console is done all I get in the browser is a page saying that the web server is running and you can replace that page with your own ones.

It appears that the upgrade altered the existing abyss.conf file slightly.
I use port 8000 for the web pages and the upgrade altered the console port setting to 8000 rather than using the default 9999 so therefore when I opened the console I got the welcome message in the web root. Changing the console port back to 9999 allowed the console page to show.
Example of abyss.conf -

I guess the lesson here is to make a backup of the abyss.conf file before upgrading!

Unable to delete corrupt ._Safari file

Close ...
Just been trying to clean up the ol’ P4 and had a problem trying to delete/rename a corrupt file.

The two files at issue were named -
._Safari 49K in size
Safari 0K in size
The files were in a folder named corrupt2.

The method used to remove these successfully was to remove the folder via the DOS command line -

rmdir /S /Q corrupt2

Dot Net Framework can’t be updated/uninstalled

Close ...
Tied in with previous post (67) - I noticed that Windows Update was failing on .net framework updates.

Tried to uninstall/reinstall the various Frameworks and it basically creates and endless vortex that will suck the life from the mortal body and make one wonder whether the product code for windows is actually 666!

msicuu2.exe was tried but didn’t appear to work so well on the Framework installs.

Anyway I found a good site that discusses these sort of issues ( ) and got links to a couple of good tools.

Cliwreg-x86.exe - used to clean out Framework 2.0 install.
Cleanup_tool.exe - used to select a Framework to clean out.

I found I needed to clean out all the Framework versions installed ( in my case - 2.0, 3.0, 3.5 and 4.0) and then restart the Virtual Machine.

After doing this I installed Framework 3.5 SP1 (which also installs 2.0 SP2 and 3.0 SP2 ) successfully and then Framework 4.0 installed OK.
