BackgroundMediaPlayer unreliability

Hi all,
I am using both MediaStreamSources and FileSources for an audio app I am building.
Using MediaStreamSources has been successful so far - app plays them reliably.
Same with FileSources, except for one problem.
If I have previously set a song using BackgroundMediaPlayer.Current.SetMediaStreamSource, and then go to play the next track with BackgroundMediaPlayer.Current.SetFileSource m4a/aac files will often play silently. Playing another song with SetFileSource
will sometimes fix the problem, sometimes not.
Asking the foreground thread to restart the background playback thread does also not solve the problem.
So in summary:
Just using SetFileSource over and over = OK
Just using SetMediaStreamSource over and over = OK
Using SetMediaStreamSource after having used SetFileSource = OK
Using SetFileSource on an m4a file after having used SetMediaStreamSource = BAM BAM not ok!
Has anyone else experienced this issue or have any advice? I'm bashing my head against the wall with this one!

Hi Alister,
Because I didn't see your code snippets, so I'm not sure your implementation was correct.
Could you please provide a simple repro sample, you could upload it to OneDrive and share with us.
For Background audio player, I would suggest you reading this article:

Voice Memo Unreliability

The voice memo feature on my 3GS is starting to be unreliable--i.e., sometimes it records just fine and other times it is running, but not recording. I installed current software (4.3.2) and thought that took care of the problem, but it hasn't. Any suggestions?

I found this thread because my Voice Memos app has disappeared, as well. It is not in search, and I only have nine app screens. I tried to restore home page layout, but it has not reappeared. Suggestions other than resetting the device?

Hi i have an i phone 4 that unfortunately is just out of warranty, and when i plug it in to i tunes shows error code 9, i am due to buy a new phone and am looking at an i phone 5, can anyone advise me if the 5 is as unreliable and rubbish like the 4

Can anyone advise me i have an i phone 4 and unfortunately when i plug it in to I tunes its picked up by the lap top but when it goes to reload with the bar on the screen it goes off and all i get is error code 9, i have tried for weeks to fix this and get no were if even tried putting on new firm ware ect but still has nothing, the sync is all grey so i cant click that, basically its a black bit of platic ive got here not an iphone and unfortunately one that has ran out of warranty. I have recently started my own company and need 4 contract phone 1 for me and 3 for my staff, i no the i phone 5 is a new phone so no will be able to tell me if its going to be as useless or unreliable as my 4,my staff are telling me to got for the 5 but im woried about waisting my money, or could any one advise me on an alternative for my lads. Thanks

Pay no attention to iinami, the amount of replies to people saying their handsets must have been jailbroken everytime iTunes throws out an error is tremendous. (Clearly you don't need to have any real knowledge to get to level 3 on these forums, let's hope apple's geniuses know a lot more than some of their customers.)
http://support.apple.com/kb/TS3694
Solution below.
Error 9
This error occurs when the device unexpectedly loses its USB connection with iTunes. This can occur if the device is manually disconnected during the restore process. This issue can be resolved by performing USB troubleshooting, using a different USB dock-connector cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.

BackgroundMediaPlayer high memory usage

Hi, I have a problem with WP8.1 Background task with BackgroundMediaPlayer. When I have just the simplest app, which have virtually zero logic in both the task and and app, when the task is started, it takes 15MB of memory. When playback starts, it jumps
to 21 MB, which leaves me about 4 MB (since the limit is 25 MB). This is just ridiculous. (I use MemoryManager.AppMemoryUsage to get used memory).
What I find even more stupid is the fact that when I run the app in emulator, the memory usage is 5 MB on start, after start of playback 11 MB. So I am left with 14 MB, which is ok.
I created a simple project, if you are interested, download it here: http://bezysoftware.net/files/App13.zip It will notify you about memory usage in background task using toasts.
Any ideas what to do? Beside rewriting everything in C++ - I already have an app ready in C#.

Hi bezysoftware,
Looks like emulator performs better than the real device? I'm not quite understand what do you mean by "playback" start, what's the difference between task start and playback start?
And sorry I cannot repro the issue on my emulator, always 7.7MB instead of 11MB as you mentioned.
I also tested with my Lumia 630, it only use 3MB when start and use 7MB when running, I cannot repro the issue.
I would also suggest you tell us what kind of device you are using, perhaps it related with the test device.

Home sharing sooooo unreliable to be unusable - will it ever be fixed?

I bought an Apple-TV-3 six months ago and decided to migrate ALL my video media to apple m4v format to use via home sharing. To this end I spent a few months developing a PC app ConvertApple to automatically re-encode/remux and tag (using moviedv/tvdb) with full metadata all my videos with no user interaction needed. It's an awesome app if I say it myself, as all other similar programs require you to waste endless amounts of your own time, whereas this program works it all out automatically. I had planned to release it a month ago but owing to home-sharing's unreliability can no longer justify doing so. I had also bought a second apple-tv, but unfortunately between the latest ATV updates and itunes, home sharing has become sooo unreliable that it is no longer usable. I sat down tonight with my family to watch a film but the circle of death when trying to play a movie returned. How embarrasing. I flicked to my windows MCE box I had hoped to replace by ATV and watched it from there.
As a developer with 30 years experience, there's little I cannot get a computer to do, but I can categorically say that although home sharing works sometimes, it is sooo flakey that it is just not a viable 24/7 solution for the home. It may work for a day or two but soon the circle of death appears and you cannot play anything, Restarting itunes, usually brings it back up, but not always. It is connected to an always-on PC, with neither apple TV's set to sleep, both on static IP's and STILL the problem persists. I also run a Upnp server TVersity on the same box, that works flawlessly, but alas until a jailbreak for ATV3 comes out allowing me to run a proper upnp client I may as well bin the Apple-tv's that have wasted months of my time on a fools errand.
I am bitterly disappointed as the only reason I went down the Apple route in the first place as I trusted their reliablility and am shocked at just how appauling their home-sharing system has become. I am planning to sell the ATV's on ebay soon and purchase Google-tv's instead and I guess rename my app ConvertGoogle! The ATV+homesharing system seemed rock solid back in April but is now unusable. I've read 100's of posts from other users alluding to this issue and get the impression apple are in denial with no plans to fix it so if you're thinking of buying an Apple-TV DON'T!
Anyone who "think's" they have a working home-sharing system, wait a few days! I doubt an uptime of > 3 days can be achived. I also fail to understand why it is sooooo slow connecting, especially from iphones. My upnp clients connect instantly + most modern TV's have upnp built in. iTunes homesharing is clearly a very badly written proprietary system and should be junked and replaced with a standard upnp client (and server), then at least apple-tv's would be usable. As a primarly msoft developer since the 80's I always (jokingly) slated Apple, but bought into them with iPhone4 and now own 2 iphones, 1 ipad and 2 atv's, but I am now considering migrating to Google kit due to Apple's unreliability. I will never buy another Apple product as I just don't trust them to be reliable anymore. STuff works but only when it feels like it. I cannot live with hardware like that!

My current status is having restarted iTunes, I can browse my library from ATV, but as soon as I click play it just sits there circling-of-death indefinately - pathetic!
Scrap Home-Sharing it's total garbage technology and implement a standard uPnp server in itunes or at LEAST add a upnp client for ATV3 we can use eg AirPlayer = works solidly on my ipad/iphone etc. Whatever happened to the ATV SDK being opened up mooted months ago?
I'll get a google-tv of Amazon this w/end and see how I fare with that. I'd live to have used ATV3's but they DO NOT work, so I can't. Oh and why on IOS6 on iphone does the remote app just close itself every now and then?
Apple need to fix things for their existing customers, rather than focus on new features to attract new ones, or they will end up having no customers five years from now!

Unreliable WiFi on Macbook Pro 8.1

Hey y'all,
I've been using arch for a few months now and everything has been going well with the exception of how unreliable my internet connection is. Basically, I don't really have a problem connecting to the internet, but after using it for a minute the internet connection will suddenly drop and the only way to get it working again is to turn it off and on again. When I first started using arch in January the same problem was happening, but happened much less frequently. With more recent updates, however, the problem has become unbearable with more recent system updates. I have a brcm4331 wireless card and am using the b43 driver. I used the instructions from http://linuxwireless.org/en/users/Drivers/b43/ to install the b43 firmware on my computer. I've searched around for others with the same proplem, but only found this https://bbs.archlinux.org/viewtopic.php?id=139911 which isn't with the same chip as mine, and the bcm4331 chip is not supported by the wl drivers. I also have another friend who's been on arch longer than I have and is having the exact same problems as I am.
Any help would be awesome! I can post any additional info that may be needed, though I'm a bit of a linux newb and may need help figuring out how to do things.

What is the wireless mailing list? Is it open to the public? I figure if I'm dealing with a chip that has little support that I ought to get on something like that if it would mean that I would know when to expect updates for it. I had seen before that broadcom intended to add 4331 support to the bcmsmac drivers, but that's been on their to do list for over a year and I don't want to wait around for them to eventually fix it. So a linux kernel patch sounds way better, even if 3.10 won't be coming too soon.

Unreliable - Deleting multiple files/folders with the same name?

I have recently found when trying to delete folders with the same name it is unreliable, is there a better way, ie termin that would work for the following...
I have 1000's folders with sub-folders to delete...
Please see screenshot each folder is identical apart from 'copy #' at the end of the folder
1. using search in top level folder toobar for "instructions"
2. 647 results are retuned
3. Select all and [cmd] [del]
4. Repeat step 1 but some folders are still are found.
Any ideas ?

Go ahead and doubt if it makes you feel superior.

HT203970 Home Sharing fix is unreliable and not permanent

Going by other posts on the Apple Forums, this fix is unreliable and not permanent...
https://discussions.apple.com/thread/6601112?tstart=0
The fact that this article exists indicates that Apple are aware of the issue yet nothing has been done to resolve it since Yosemite was released over 3 months ago. As of 31st January, I am running OS X 10.10.2 with iTunes 12.1.0.50 and the latest Apple TV firmware yet this issue still occurs.
As with other people that have encountered this problem, one of the suggested fixes may work but none of them are reliable i.e. one may work one day, another on a different day and some days I can't get it to work at all. Some of the fixes that have worked at one time or another are as follows: -
Reboot the Apple TV (this is the simplest fix but now works less frequently than it used to)
Restart iTunes
In "iTunes > File", turn off Home Sharing, turn Home Sharing back on again and restart iTunes
In "System Preferences > Sharing", change the computer name then restart iTunes (this is the Apple recommended fix).
In "iTunes > Preferences > General", change the library name and restart iTunes.
Turn off the "iTunes > Preferences > Sharing" functionality. Some people have commented that this conflicts with the Home Sharing feature. I don't know how or why let alone what the difference is between Sharing and Home Sharing. The Apple documentation is a bit ordinary in this regard.
Various combinations of the above or the reverse.
I don't know if this problem is related to the OS X Computer Name automatically changing issue ...
https://discussions.apple.com/thread/6631728?tstart=0
I have that problem as well so I tried a workaround for that problem...
http://ispire.me/fix-yosemite-rtc-alarm-wakeup-issue/
The computer name has stopped automatically changing but the Apple TV still has problems.
Any ideas?

Lumia 720 - Highly Unreliable - phone, NOKIA servi...

Hi Nokia team
I bought a new Lumia 720 from Spice Mobile Nokia dealer about 4 days ago and it has started giving problems now. My phone went dead even with full battery. It was really unexpected and disappointing that you buy a Rs. 18000 phone with no reliability of the phone or service. The dealer shirks of his earlier claims that he will replace my phone in the first 7 days of anny problem. He now clearly says no - such cheats you have your dealers as. They dont even know your policies or give false claims - marring your reputation in the market. Then I went to Nokia Care center only to find that they treated me with no sympathy but rudely to tell me that the phone can have such issues and that they dont have any policy to replace the phone. What they did only was to update the software and told me that the phone is fixed. But I have been finding this problem of the phone getting dead almost every day. After it is dead and we try to open it with all 3 buttons, it removes all my previous messages and calls data from the phone memory. It hangs at times when many applications are open. How unreliable it could be!! Or is it so badly that LUMIA works unlike shown in its advertisements?
Why the hell would I want to get my phone repaired right in the first week? Why cant Nokia do enough testing before releasing its handsets or just replace the phone when it is found faulty.
I have decided that if Nokia does not replace my phone now even, I will move to the Consumer Court against both Nokia and its dealer.
Please contact me asap if you want to save a particular consumer community. Yes, I am really frustrated by your product and service.
Thanks

Why is the mail application so unreliable?

I have made my move to a Mac laptop this year after being overrun with iOS devices in my house. The MacBook Air I have is an awesome machine. One of the main things I got it for is for business productivity. The simplest of things I should be able to do is communicate over email, but the native mail application is so unreliable it is embarrassing. I have a yahoo account that I was able to setup fine enough. Every time I send an email it is a gamble as to whether or not it is sent or not. That is unacceptable. The mail accounts I setup on my iOS devices seem to be bulletproof and it boggles my mind that the mail client on the Mac OS is so bad. I wasted time with the support lines on several occassions and all they could tell me is tht sometimes after I send an emal it can get stuck in between sending and getting off the yahoo server so there is no record it has been sent and no copy in drafts. What an awful answer. It has gotten to the point where the only way I am confident to use email is on my iPhone or through the web browser on the yahoo site. I am really unhappy about this and would like to know if other people see the same problem.

I'm spending hours with the techies on my server, which is the cable company we contract with. First I kept getting the message that Mail didn't recognize the server but it would connect when I clicked Connect. Then it started letting me receive messages but not send. Now I can't do either, and the company has no help for me. I have run the disk utility verify and repair options and it tells me all is well.
I don't want my emails anywhere on the web, just here at home. The cable techs have gone over and over the technicalities on their end and have concluded that Apple Mail is the problem. I find evidence of that in much online grumbling, but here I find only self defense.
How could you help me?
1. Admit that your software has bugs. Tell me some things I could try to get my email working again. I'm finding such protocol elsewhere on the web but it all seems to relate to earlier versions of OSX.
2. Show me where I could upgrade to a less buggy version than 6.2. This is my second laptop in the past year (first one stolen) and each had different problems with Mail. The first one kept losing mail. Messages would come in and then be gone when I'd go to answer them. Important items I would not delete. That's not happening with this one -- it just keeps losing connection with my server.
Please stop pretending that anyone who has problems with Mail is afflicted in some way. There are problems, and I'm very shocked that Apple, who used to be one of the good guys (at least in my book), seems to to be stuck on a policy of self righteousness. Guys, your halo is tarnished with Apple Mail -- time to realize that and cope.

Unreliable sound - speaker symbol greyed out and red light in 3.5mm jack

Had my MacBook for 3 years with no problems. But over the past few months, the sound has been very unreliable. It always works when external speakers are plugged in, but when using the internal speakers it's very temperamental. It will just suddenly grey out the speaker symbol on the menu bar at the top, and a red light is visible in the 3.5mm jack socket.
Any ideas???

Your Mac believes that a digital audio cable is plugged in. You can use a toothpick or unbent paper clip to toggle the DA switch off. It's located along the side of the port, not at the back whence the light emanates.

P55t - External 4K HDMI monitor connection unreliable

I have a new Satellite P55t laptop with 4K integrated display (PSPNVU-03004P).
I have a 4K monitor connected on the HDMI port. Running Windows 8.1.
It works sometimes, but for some reason is entirely unreliable - it seems to lose contact with the monitor, which puts all the windows off the external display back onto the main display - the main display constantly flickers as if it is trying to connect to the external monitor again, etc. etc.
I have a short HDMI cable (600mm) which works fine with this display and another PC.
Intel HD Graphics 4600 driver version 10.18.10.3412

Toshiba staff monitoring this - isn't it time you took major issues like this seriously and made some contribution to the forum?
Is there any reason why I can't install the most up to date Intel HD 4600 Graphics drivers?

Mobile homes unreliable and unstable

We are having major problems with Apple's mobile home sync. I hope you can help. I will also contact Apple support. When I hear something useful from them I will get back to this topic and add the info.
We have a studio of 20 graphical workstations and we've had issues that users did not backup their home folder/work. After a lot of discussion and contemplating we bought a new server for mobile homes. So, users have their home folder where they do all of their daily work and every morning and evening when they login and when they logout their home folder is being synced to the server so that all their latest work in on the server. The server is being backupped every night so in this way all data will be backupped and save. That was the idea…
But unfortunately mobile homes seem to be very unstable and unreliable and we are having several issues. Although people login and logout every day without any problem and homesync informs us that syncing goes fine it doesn't sync everything. All home folders are having issues. When I check the backup the most recent data is not in the home folder where it should be. When I check the home on the server it isn't there, or documents are there but not the latest. When I check the home on the workstation it is there where do user put it. When I check the sync status it says everything is OK and the latest sync is of that day. So that is (major!) issue one.
Issue two is that I've had two users complaining that they move their data around in the home folder, just doing their work, and when they log in the next day their data is on the OLD place AND the NEW place. Very time consuming for them and confusing and it is very obvious that the sync process doesn't work.
Another issue is that I've had a couple of users already complaining that when log in they get sync errors. Nothing major in most cases, a file being in use or something and the next sync it syncs without a problem. But now for 3 users it seemed that their folder had problems syncing and whatever I do, I cannot get the folder to sync again, without any clear reason in the logs. I end up deleting everything in their home on the server, delete all appropriate sync caches, preferences, the FileSync folder in the library and the .FileSync folder in home and thus creating a new sync again. Only then when I do the first sync, the syncing process starts working again.
Important to know is that every user has their own workstations and that they do not change workstations. So in that regard they have all their data in one place, THEIR workstation, and that data has to sync one-way: to the server. I could imagine that when people change stations on a regular basis it is hard for the sync system to keep up with the latest changes, but that can't be the issue here.
Any help, tips, solutions, comments, etc. etc. are very much appreciated.

Slow Boot, Unreliable WiFi, and Forced Shutdowns

Ever since I got my iMac, I've been having the same problems quite consistently for over a year now. The WiFi used to randomly drop out (as many others had also reported), but that was fixed. Except an OS update or two later and it's back (although it's different and not quite as bad). Anyway, here are all of the problems I've been having:
– iMac is slow to boot; sometimes it won't boot unless I unplug my Firewire cable. For a fully-upgraded iMac, it shouldn't take as long as it does (upwards of a minute). Sometimes, however, it won't boot at all. It will get stuck at a grey screen (or login screen when I have that set up) with the cursor visible. The computer will not continue to boot up or receive any input until I unplug my external Firewire hard drives.
– WiFi is somewhat unreliable. At times, my internet connection completely drops out despite having a full-strength signal. Oddly, it usually happens right after I start to use the internet after having been away for a while. In other words, it works great when I'm not at the computer (if, for example, I use LogMeIn), but as soon as I sit down at the computer, I can visit one website before it drops out on me. I end up turning WiFi off and back on again and hope that it works.
– Finally, I can't remember the last time I did a legitimate shutdown. Every single time I go to shut my computer down, it never does it by itself. If I let it do its thing, some app won't quit and will cancel shutdown. The only way I've been able to remedy the problem is by clicking Shut Down then force-quitting literally everything. I've read that the problem tends to be Mail as it tries to keep a connection with the mail servers, but it's been anything from App Store to Safari to iTunes. I have a problem report handy from when I last shut my computer down if that's worth posting.
Thanks for taking the time to help me figure this out!
