ALSA randomness, sometimes works, sometimes doesn't

I'm having some very strange problems with ALSA
I updated my system and had some issues with it, so changed to OSS. Then found more problems with OSS because my programs aren't compatible with it and I just want to go back to ALSA.
I can do an 'alsaconfig' command in the terminal and sometimes it'll find the card, sometimes it won't.
on bootup sometimes ALSA will initialise and i'll get sound the whole session, but on a reboot I won't.
I've followed the wiki pretty well and everything was working for 4 months then an update has stuffed it up
I'm on a clonezilla backup at the moment and this one is even playing up, for some reason i've got sound coming out of my virtual box, but not arch, this will usually happen if i try to play music out of Rhythm Box. That gives me the error " Couldn't start playback, The autoaudiosink element is missing."
what's happening?

Compositing in KDE sometimes doesn't work on Nvidia hardware

I tried searching whether similar issue was already discussed on the forums, but didn't find anything; sorry if I missed it.
I have two different systems with Nvidia hardware, one with a 9500M GS, and another one with a GTX 580. After updating to KDE 4.11 (as far as I remember, this issue started appearing at about that time; now it still happens with KDE 4.12) compositing in KDE sometimes doesn't work. By "sometimes" I mean that once in a while I boot the computer and compositing isn't working, then I reboot and everything is fine. Sometimes hitting Alt+Shift+F12 twice helps, but sometimes it doesn't. I didn't gather statistics, but it seems to happen on the 9500M GS system more often than on the GTX580 one. On the former it happens once in about three boots, while on the latter it's something like once per ten boots, but I may be wrong.
I use proprietary driver, since I sometimes use the computer for gaming, and the opensource driver is still not quite up to the task. Btw, games work fine even when compositing doesn't work.
I haven't noticed any similar issue on my other machine with Intel graphics.
If anyone could help in identifying the cause, I would be much obliged, because I have no idea where to start searching.

Good guess but even if I miss the word or any text, in normal use it still brings up the menu (with options limited to 'zoom in' and 'zoom out'). When I'm not getting the menu for word correction I'm not getting any menu in the body of the document at all - it's strange!

A little uncanny situation since release of FIREFOX RC is that 'Reload option which used to come under view option is no longer visible,but appears as an icon in toolbar...which sometimes doesn't work'. Please try to fix it if its only my problem

I have been using FIREFOX since a long time back and am quite happy with FIREFOX 4.
But a little uncanny situation since release of FIREFOX RC is that 'Reload which used to come under view option is no longer visible,but appears as an icon(button) in toolbar...which sometimes doesn't work(becomes blur and sometimes firefox hangs)'.
Please try to fix it if its only my problem or include it in next release.Thanks!

Unload All Modules sometimes doesn't work with LabVIEW

TestStand's File >> Unload All Modules (and its RunState.Engine.UnloadAllModules() function) sometimes works and sometimes doesn't (with LabVIEW). When it doesn't, I have to quit LabVIEW to make TestStand unload LabVIEW VIs, otherwise I can't edit them.
Is there an "Unload All Modules" command that works all the time?

Hm, i assume that you have callbacks defined which do call those modules. Possible callbacks to look first are: SequenceFileLoad/Unload, FrontEndCallback.
Another possible reason is that there are components running in the LV RTE (runtime engine) calling into the VIs you try to debug/modify in the development environment.
Can you pinpoint the "lock" to specific sequences/modules? Do they lock only after specific sequences/modules have been executed?

The home button of my ipt4g sometimes doesn't work

the home button of my ipt4g sometimes doesn't work what should i do???

I have the same proble. I have heard multiple accounts of people going to the apple store with this problem and apple gives tham a brand new ipod.

Finally got round to buying an iPhone 4, really excellent to start with. The sharing of music from my Mac Mini was excellent. ios6 update has ruined all that! The artist view miss's out most of my music and the sharing sometimes doesn't work at all!

How do I get this feature working again? I am reluctant to move to iTunes 10.7 because I don't trust Apple at the moment.

My suggestion:
1) Always using MAC AIR with the power plug in.
2)Don' let the power level of battory fall under 30% percentage.
3)If the MAC can't be recharged now, just let it be with power plugged, WAIT...

Headphone jack sometimes doesn't work for my ipad air.

Headphone jack sometimes doesn't work for my ipad air, when watching a video or listening to music the audio in the ear or head phones cuts off. It's definitely not the ear phones it's the ipad because I've tried too many different headphones. It's been 7 months that I've bought it from the apple store so would you be able to fix it. Is there a fee?

Hello SungSungE,
please check out this thread: https://discussions.apple.com/thread/6288240
It doesn't perfectly answer your question but you will see that I have an answer from Apple regarding this problem.

MacBook Air (Late 2010) keeps shutting off randomly, sometimes when computer is tilted or moved

Hi all,
I have a Late 2010 13-inch MacBook Air. I've had it pretty much since they started selling them at the Apple Store, or maybe a few months afterward. For probably a few years I had only used it once in a while, since I had a Windows laptop for work. Since this past December I have exclusively been using my MacBook Air, I have since given away the Windows computer.
Recently it has started shutting off randomly while I'm using it. I've tried resetting the PVRAM and the thing that manages how the power/screen works (I forget what its called), and that hasn't worked. I'll try to turn it back on again after it has shut off, and it sometimes doesn't come back on unless I tilt it a little bit. Does anyone know what could be causing this issue? Is it something I can probably fix, or should I take it to the Apple Store? Thanks for any and all feedback.

Since the PRAM and SMC reset didn't work and your screen only seems to work when the screen is tilted at a specific angle, it might be a hardware problem. If you're near an Apple Store, you should make an appointment at the Genius Bar to have someone look at it: http://concierge.apple.com/reservation/us/en/techsupport/

Browser plugin sometimes doesn't display PDF, just a blank region

Hi,
I'm running Slackware 13.37 (32-bit), with Adobe Reader 9.4.2 and Firefox 5.0.1. I have the browser plugin installed, but sometimes it does not work. As in the thread title, the document fails to display, with just a black region appearing in the browser. Sometimes, if I refresh the page a number of times, I can get the document to display. Sometimes just waiting seems to help, but not always. This isn't restricted to one particular document. It happens (seemingly) at random. sometimes a given document will display in the browser, but not at others. I can't seem to reproduce the problem consistently, making it harder to fix, I suppose. This does not seem to be a problem with my Firefox profile; I started with a new profile and the problem still occurs. The Firefox error console gives no messages pertaining to the problem :/.
Any ideas?
Thanks.

I'm seeing the same on 32-bit Fedora 15 with:
firefox-6.0.2-1.fc15.i686
nspluginwrapper-1.4.4-1.fc15.i686
AdobeReader_enu-9.4.2-1.i486
If I kill any pdf plugin process like the following:

then it works again. I'm going to try running without the wrapper for a bit. Won't help my 64-bit users though.

My computer sometimes doesn't send out my e-mails

My MacBook sometimes doesn't send out my e-mails. I need to send them directly from the server to be certain they go out. Random recipients and random e-mails.

Hi CamarilloJuls,
Welcome to Apple Support Communities.
It sounds like there is an intermittent issue sending emails from your Mac. The article linked below provides a lot of great information and tips that should resolve most issues related to sending email on a Mac.

Upgraded to IOS 7 and phone sometimes rings and sometimes doesn't

Upgraded to IOS 7 and phone sometimes rings and sometimes doesn't. What's going on? I've missed several calls but my phones been sitting right in front of me (Yes, the sound switch is turned on on the side)
What's going on? Its Random!
John

Your phone might be on do not disturb mood... So, when it's locked, you receive no calls. If you see a crescent at the top of your screen, go to setting, do not disturb, and turn off the manual
Hope that help

My Macbook sometimes doesn't connect to my Wireless N network

I had my topcase replaced by apple a few weeks ago. Since then I've noticed my macbook SOMETIMES doesn't connect to my wireless N network (from my AEBS running on 5.8ghz frequency).
It's strange because most of the time it finds the network fine. But sometimes when i open the macbook up (awakes from sleep) it doesn't see the network (it's not available from the list of available networks). If i try to connect manually to the network when this happens i get a "connection timeout" message. If i turn off my airport connection off and then on with the macbook (thru the menu bar) it sometimes finds the N network. Sometimes that doesn't work, and i have to put the macbook to sleep and hope it finds the network when it awakes. Sometimes that solves the problem, but i may have to try it 3 or 4 times.
If i switch my AEBS to a mixed signal (supporting G) i don't have these problems, but i shouldn't have to do that, and i'm sacrificing wireless speed if i do that. I have a stable connection when it DOES find the network (it won't drop out and will be at full strength) but as soon as i put it to sleep i run the risk it may not find the network when it awakes.
As i said before i didn't notice this problem before I sent in the macbook to have the topcase repaired - is it possible the airport card was damaged? I was only running a N wireless network a week prior to submitting the macbook for repair, so i'm not positive that's it either.

There's a reason why some are less than energetic in answering your question: the "pinwheel of death" could mean a lot of things. To start off, you will need to use various utilities to coax your MBP into functionality:
1. Perform a Permisions Repair, and also Repair your disk on Disk Utilities. If this doesn't work, proceed to the next step.
2. Using a free utility like Onyx, clean your caches.
3. Using the free Kext Wizard, make sure your files are consistent and accurate.
4. Use OpenDNS by connecting to this link:
https://discussions.apple.com/thread/2478039?start=0&tstart=0
OpenDNS is a simple way of making your online experience faster and easier.
If these steps were successful, take the time to post here; others will profit from your experience. If you still don't have the answer, post...and we'll find the solution!

Sometime doesn't

Good Morning Everyone,
parent, child
master, detail
Primary, Foreign
Attribute, column
Entity, Table, relation
Tuple, row, record
Create, delete, alter, truncate,
tables with Join - outer, inter, cross,
Cartesian product
nested queries
select, From, Where, And
Sometime works but sometime doesn't.
Can I get a informative book, links, any?
Thanks,
NY

Hi Boneist,
I think you need to feed us with tables (create table ...; insert into ...) else nobody can help you because we do not know what your table structure is.
If you want to learn how to write hierarchical queries, then have a look at the SQL references (links posted earlier), it pretty good explained in the Oracle docs.
For specific cases somebody will help here if there is enough detailed information.
best regards,
David.

GNOME desktop sometimes doesn't appear

When I start computer and load GNOME through GDM, GNOME desktop sometimes doesn't appear. Both panels appear but wallpaper and icons don't appear, only gray background. I should press Ctrl+Alt+Backspace to reload X Window and after it desktop appears. How to fix this problem?

I removed KDE 4.1 several days ago, installed GDM and wrote it in DAEMONS list to launch in /etc/rc.conf. On my work computer I have "clean" GNOME and never installed KDE there. And on my work everything is ok. Maybe I still have any remains of KDE on my home computer which make this problem?

The answer helped me.But still, what are the settings that I have to change for the behavior of the mouse pointer towards finder? Also the mouse pointer sometimes doesn't accept my command and start clicking itself.what is the problem and how to fix it?

If the mouse clicks something on its own then it looks like you have a hardware problem with the trackpad or possibly the battery that is right underneath the trackpad.
I have read that the battery can swell and that would put pressure on the trackpad.
