Bluetooth performance with Keyboard and headphones

I have three bluetooth devices - Dell Keyboard, Magic Mouse, and stereo headphones. Whenever I play music and start typing on the keyboard, the music stops playing until I stop typing. Is there a fix for this?

Only thing that comes to mind is to get a second BT dongle, and then hope the two don't interfere with one another.
BT is a very low bandwidth protocol. Only about 1-2Mbps, and pretty much all of that is going to be taken up by streaming music. So you're going to have to make a decision about how you go forward from here. Something is going to have to give, and you have to decide what that something is.

Losing bluetooth connection with keyboard and track pad

Every few minutes, I lose the connection between my wireless keyboard and track pad and the computer. Since its happening simultaneously, I don't think its an issue with either the trackpad or keyboard but bluetooth. I've tried turning my computer off and unplugging it and no dice. Its a real productivity kill right now. HELP!!!

Hey all - thanks. I've tried swapping batteries and my battery power is 100%. I've turned the computer off completely and back on. I've even unplugged it and turned off the keyboard and track pad.
My computer will not let me turn Bluetooth off. It give me a warning sign that I won't be able to use the computer and the only option is ok.
I'm also not having any luck finding out the RSSI levels to see if there's any interference. As far as I know, there are only three devices via blue tooth and I turned off one (my iPhone) and the only other two are the track pad and keyboard.
When I try to follow the RSSI instructions, the option - click doesn't do anything. Very frustrated and thinking I'll need to schedule time with Apple. Today has been very frustrating.

870A Fuzion Power has problem with keyboard and mouse movement only in games.

Hey guys,
recently built a new system and chose to go with the 870A Fuzion Power mainboard, everything has gone very smoothly execpt for one problem, only when I play games like Crysis 2 ect the mouse seems to jolt around now and again and the keyboard decides to stop responding if I hold down the movement keys, and this is only in game not surfing the web for example. Now, I am using a wireless mouse and keyboard but I plugged in a PS/2 keyboard and the exact same thing happened. I've installed all of the drivers that came with this board and the drivers for the mouse and keyboard. Any of you guys ever had this sort of problem or know how to fix this?
Thanks.

I bought a new Macbook pro in june 2010, I didn't have any keyboard or mouse issues prior to upgrading to 10.6.4 supposedly this update was made to fix some issues with keyboard and mouse becoming unresponsive. For me the opposite happened. after the upgrade, my keyboard and mouse (trackpad) becomes sometimes partially unresponsive or totally unresponsive. the only way to solve the problem is by completely turning of the computer and turning back on.. granted it doesn't happen very often.. generally once every about 2-3 weeks but it is still annoying though..
I didn't have a chance to use the computer too much on the previous version (10.6.3) so I don't know if it is software related or hardware related.. any thoughts?

Anyone having Bluetooth issues with mouse and keyboard with mountain lion?

Installed mountain lion yesterday and since the restart my bluetooth on my computer is not working properly and it says "bluetooth not available" Any ideas or suggestions on a fix. I have already tried re installing mountian lion with no luck.

Did you try these steps? They worked for me and a couple other people:
1 - Turn on automatic login: System Preferences > Security & Privacy > General > Click the lock to make changes > If Disable automatic login is checked, uncheck it > Pick your user account and password > Ok.
2 - Shut down your computer.
3 - Turn off your keyboard and mouse: For keyboard and wireless trackpad you hold the power button until the light goes off.
4 - Start your computer.
5 - Once your desktop has fully loaded turn the keyboard and mouse back on, everything should work.

Lost bluetooth pairing with mouse and keyboard

Less than 100 days out of the box, my iMac has lost the connection to both the keyboard and the mouse.
As of this afternoon, both devices have brand new batteries. When I turn them on, the light stays steady for a few seconds, then blinks, then goes off.
Bluetooth is turned ON.
"Discoverable" is checked.
I removed both devices from the list, thinking maybe they needed to be reinstalled. I am able to locate them, but keep getting messages like these:
"The pairing attempt was unsuccessful. This configuration of Mac OS X and Bluetooth software could be invalid or unsupported."
"The pairing attempt was unsuccessful. Make sure your device is in range of this computer, turned on, and discoverable.
On a couple of attempts with the keyboard, I've gotten a message providing an 8-digit passcode which I'm supposed to input, but typing it on the keyboard doesn't do anything. I've tried adjusting that setting to not require a passcode, but that makes no difference.
(Funny, when I Craigslisted my old computer I had a hunch I'd better hang onto the mouse and keyboard; good thing I did, or I'd be completely out of commission at the moment.)

Thanks. I just re-set the PRAM and then tried reconnecting both devices as suggested. I'm still getting nothing. Both devices are now showing up under the bluetooth menu, but I can't connect to them ... not from that menu, not from Bluetooth preferences, and not from the keyboard/mouse preferences. And they're definitely turned on, with brand new batteries, and all within two feet of the computer.
Speaking of bluetooth preferences, could I have knocked them out of whack somehow? I see File Sharing Settings and Advanced Settings; what should actually be checked in them in order for this to work? Looks like I have System Preferences Version 7.0, running with OS 10.6.2. Under "Serial ports" I have only "Bluetooth-PDA-Sync" listed, Type RS-232, and that's checked on. There's another checkbox underneath what looks like a key icon, and that is NOT checked.

Poor Bluetooth performance with all aluminum Mac Pro

The all aluminum case for pre-mavericks Mac Pro is the primary reason for poor antenna performance of Bluetooth. Aluminum, being a good conductor, acts as a reflector of EMF forming what is known as a Faraday Cage, essentially trapping emissions within the box. Normally, holes drilled in the case would allow enough EMF to pass through the case but the hole size for transmission is directly proportional to the lowest frequency that will pass through easily. An example is the typical microwave oven where the window is actually a conducting sheet with small enough hole such that higher freq light waves pass easily through the sheet but lower frequency microwaves do not. Perhaps if the drive bay covers were made of plastic, transmission of the Bluetooth and wifi would be sufficient. One might carefully nibble a slot or two in the side door but this would surely invalidate any warranty and care would have to be taken not to get aluminum particles inside the computer. This would probably nullify any FCC approval of the machine due to clocking noise interference with other devices. The best approach would probably be a tuned waveguide that passes frequencies only around 2.4 GHz ~ 5 GHz through the case (very similar to the way tuned ports on audio speakers pass a band of frequencies needed to extend bass response). I'm sure Apple will have corrected this design flaw in the new Mac Pro introduced this year. If you have lots of time on your hands you can get a college level text on electromagnetics (Maxwell's Equations, etc.) and derive all the details but with a bit of experimenting and reading about tin can antenna mods to wireless routers you should be able to improve Bluetooth performance significantly.

Thanks for the suggestion. I will have to move my wireless home base station. It is on the same desk as my mini so much less than 5 feet away.

Recording a live piano performance with GB and iMac internal mic

I am a complete novice with GB. My iMac sits six feet away from my piano, and in a few days my piano teacher will play a concert on it. I am into digital photography, but have no video recording equipment. Can I record this performance using GB and my iMac internal mic, and, if so, how? I would understand completely if you refer me to an article or other secondary source where this is covered.

You will certainly benefit from the mic upgrade. Be aware that most "studio mics" require a microphone preamplifier to bring the level up to something that your computer will be able to see (as well as to provide power if the mic requires it). If the connector is the type that looks like a headphone plug which will fit in your computer input, you are probably ok.
The recording quality will normally be determined by the format and settings instead of the application you are using to record. Stick to 16 (or 24) bit, stereo .aif files and you should be fine. The standard for CD recording is 44.1kHz.
For some information and advice on recording piano, there is an article on my website here: http://doghouseNYC.com/articles/piano1.htm
Good luck!

Problem with keyboard and audio on Satellite L40

Hi everybody,
I just installed XP SP2 on my Satellite L40 (BTW thanx to all you that have helped me overcome the problems during this operation with your threads), but I have some problem with my keyboard. I have an azerty keyboard and after I installed xp, it worked as a qwerty, I repared it, now all my letters are working fine, but i have some problems with some symbols, such as @, !, _,if you understand me.
Could somebody help me???
I also have problems with my audio, in fact I have no audio at all, in control panel it says that no audio device is found.
I saw some threads that said that I should first install kb888111, and another likely thing, but i can't find the other one. I've downloaded the sound driver from the toshiba website; thanx for helping me in that field also.
bye

I have the same problem with sound...I have found hotfix kb888111 and I instaled that one...but when i wanted to start instaling sound driver a popup window say thet there is some error and can't continue with instaling sound driver...
I found hotfix kb888111 in this folder which i have downladed from toshiba site: english\sound driver\mshdqfe\win2k_xp\us\kb888111xps2....
i do not know what to do.....Does anybody else knows....

Problem with keyboard and mouse pm8m-v

I have gotten this pm8m-v from a freind who knew nothing about computers. He had problems with the keyboard and mouse not responding at start up or just freeze on him. So I check it out, called MSI and even sent it to them, they claimed that there was nothing wrong with the board. So here are the specs of the computer now:
pm8m-v motherboard
2-256MB memory PC-2700 DDR 333Mhz
intel P4 2.6GHz
codegen power supply 300W
gateway CDW
western digital 40 harddrive
the rest is on board stuff
the problem is still there and it is driving me crazy, can you please help?

I had the same problem with the PM8M-V, today as a matter of fact, and I kept getting locked up at the point where I had to hit enter to load the WinXP CD to setup the system. After finding this topic I tried a different keyboard. The one that was being used was a Kennsiington PS2 cheapo, I swapped it for a Microsoft (one of those ergonomic styles and I've had it for a long time) Keyboard PS2, and the problem went away. I'm typing on the Kennsington right now, so it's fine just wasn't liked by the PM8M-V for some reason.

Performance with MySQL and Database connectivity toolbox

Hi!
I'm having quite some problems with the performance of MySQL and Database connectivity toolbox. However, I'm very happy with the ease of using database connectivity toolbox. The background is:
I have 61 variables (ints and floats) which I would like to save in the MySQL-database. This is no problem, however, the loop time increases from 8ms to 50ms when using the database. I have concluded that it has to do with the DB Tools Insert Data.vi and I think that I have some kind of performance issue with this VI. The CPU never reach more the 15% of its maximum performance. I use a default setup and connect through ODBC.
My questions are:
1. I would like to save 61 variables each 8-10ms, is this impossible using this solution?
2. Is there any way of increasing the performance of the DB Tools Insert Data.vi or use any other VI?
3. Is there any way of adjusting the MySQL setup to achieve better performance?
Thank you very much for your time.
Regards,
Mattias

First of all, thank you very much for your time. All of you have been really good support to me.
>> Is your database on a different computer? Does your loop execute 61 times?
Database is on the same computer as the MySQL server.
The loop saves 61 values at once to the database, in one SQL-statement.
I have now added the front panel and block diagram for my test-VI. I have implemented the queue system and separate loops for producer and consumer. However, since the queue is building up faster then the consumer loop consumes values, the queue is building up quite fast and the disc starts working.
The test database table that I add data to is created by a simple:
create table test(aa int, bb char(15));
...I'm sure that this can be improved in some way.
I always open and close the connection to the database "outside the loop". However, it still takes some 40-50 ms to save the data to the database table - so, unfortunatly no progress to far. I currently just want to save the data.
Any more advise will be gratefully accepted.
Regards,
Mattias

Conexant Smartaudio HD - No Bass with subwoofer and Headphones

Hi,
I'm using a Satellite L70D-A, I when I plug a subwoofer into the audio port, the overall sound is different, like no bass
I plug in headphones and it is the same
Is it have to do with software or hardware? I'm on Windows 8
Edit: Found a solution. I uninstalled the Conexant Audio driver at Task Manager, restarted when prompted, then it installed a workable Audio driver. I did this once or twice until it worked.

mate,
i have the same problem....
i have a Pavilion g4 1104dx laptop and my bass is completely GONE.
I plug in my ipod to my external speaker system and its perfect... but through the audio jack its horrid.
i've played around with troubleshooting and loaded the SRS Premium sound file... but it did nothing so i deleted it again (as you also found).
All my levels on my system equalizer seem normal and my itunes eq is normal also...
what is this random problem?????? does anyone know????
I called tech support at HP and they tried to charge me 50 bucks as its out of warranty lol...
thanks

Helix will not connect with keyboard and touch pad

This is kind of wierd. It's been doing this since I've owned it. I have a Thinkpad USB 3.0 port replicator. When I get to work, I used to turn the screen around backwards on the keyboard and plug it into the PR. That way all you could see was the screen. Now I have a tablet stand and I remove it from the keyboard and set it in the stand. The problem I'm having is that when I have it reversed on the keyboard OR off of the keyboard all together for a period of time (say, 30 minutes) and I re-attach it to the keyboard, I can't use the keyboard or trackpad unless I press the power button for 20 seconds and hard reset the tablet. It see's the battery and plays the audio that tells me it see's it, but the pad and keyboard are unresponsive. It's frustrating. A standard reboot/restart will not fix the problem. I have made sure my tablet and keyboard have the latest BIOS and firmware updates.
SMBIOS - 2.7
UEFI Bios - 1.27
Embedded Controller Version - 1.21
It's frustrating to have to force a restart every single time I want to dock it after it's been off the keyboard for more than 20 minutes.
Any idea's?
Gavin

Does Axis say it is compatible with a 4G iPod with iOS 6.1?
Sometimes this works
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.

Enhanced Performance USB Keyboard and Microsoft Officde

Just purchased the above keyboard to use on my new T61 running Vista Business 64. Soon discovered that the assignable keys (Rapid Access) wouldn't open Microsoft Office programs (even though two were by default assingned to spreadsheet and word processor. A complicated conversation with tech support concluded with my being told that that was "as planned" -- the the keyboard software was configured to NOT run with Microsoft Office. Not only am I unhappy that I wasted $39. but I'm astonished that folks at Thinkpad actually let this go through. This all assumes that the person I spoke to at Support was telling the truth; if not, I'm even less happy.

Actually you can assign the keys, I finally figured it out myself after lots of searching and I also had no results from Tec Support, it has only taken two years!!
Anyway, I put the disk that came with the keyboard and mouse in my computer and did not run it. I went to "my computer" and looked to see if there is a manual on it.
Go to the DRIVERS folder, XP folder, KEYBOARD folder, then click on the Readme.txt file, it will give you instructions.
I assumed because the mouse and keyboard worked I did not need to install any software, WRONG.
Good luck, I hope this helps.

I have a 2011 iMac 27" i7 and the bluetooth connected trackpad, keyboard, and mouse all go haywire after awhile. This just began today and cannot make the issue go away. Nothing was downloaded, no software updates, etc. please help!

Oops, sorry, using my iPad for this. My iMac's Bluetooth-connected devices are going haywire after awhile of use. All three things--the trackpad, keyboard, and mouse--act up, especially the trackpad, by being overly sensitive and often just clicking and moving on its own. I've restarted the computer, I've swabbed batteries out of the devices, and nothing has worked so far in solving this issue. I downloaded Lion when it came out and had the update last week (I think), but today is the first day to experience this issue and nothing was downloaded today. I've been sending out a flurry of emails, but nothing else to hint at why this problem happened. Any ideas??

Humm, thank you. I have my iPhone and iPad on the wireless network, and yeah--using the rechargable batteries. I'll try normal batteries and re-join the phone and get back to you. May take a day or so because the semester starts today. Thank you again.
