No Mic Sound with Pulseaudio, works fine with Alsa.

Have a Acer Aspire One D225E that I've set up with Gnome 3. Everything seems to be working except I'm not getting any sound out of my microphone. I've messed around with the sound settings in the gnome settings app with no success. Using alsamixer, I've made sure the mic channel is unmuted.
I'm able to record sound with Audacity using Alsa and play it back fine. When I switch to pulseaudio however, I get nothing. This wouldn't be a problem, except skype only allows you to use pulseaudio to record if you have that installed.
I've checked the wiki troubleshooting section on Pulseaudio and found the section on Acer Aspires, but solutions in the link led to a dead end. Nothing has worked so far that I've tried.
Here's my sound device:

Hopefully someone with more knowledge of pulseaudio will be able to point my in the right direction on this one.

I have exactly the same problem with my Acer Aspire 3820. It's definitely pulseaudio related, since arecord works.

I've been struggling for months, but still no answer. None of the volume tweaking tricks work, obviously, and I couldn't find any useful answers in the PA mailing list.

Have you got notifications muted ? Only notifications (including games) get muted, so the Music and Videos apps, and headphones, still get sound.
Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad above the volume switch, or via control centre : swipe up from the bottom edge of the screen and it's the right-most of the 5 icons in the middle of it (if the icon is white then it's 'on', tap it to turn it grey and 'off'). The function that isn't on the side switch is set via control centre instead : http://support.apple.com/kb/HT4085

With 10.2 I can only use system speaker output for audio, NOT my RME FF400 I used previously. The FF400 works fine with other apps. How can I set this device in FCP 10.2? (it is set in both system preferences and midi)

With 10.2 I can only use a system (e.g. speaker) output for audio, NOT my RME FF400 I used without any problems previously. The FF400 works fine with other apps (some like TwistedWave) setup in the program, and others (like Spotify) using system preferences & audio midi setup. How can I set the FF400 to be the sound output device in FCP 10.2? N.B. The FF400 is set as sound output device in both system preferences and audio midi setup.

From the fcp.co forum. See if this does anything for you.

I have the solution! Well it at least worked for me. This is the response I got from Apple, Can you please try the following steps towards fixing your audio issue, and report back with your results?
1. Open the application Audio Midi Setup (located in Applications : Utilities)
2. Select the Output Tab for the current output device
3. Select the Configure Speakers option
4. Select the Multichannel tab
5. Change the setting to Stereo Now mine was set to stereo but the left channel wasn't showing left. re-clicking on stereo reloaded the settings and after clicking apply it worked.

TS3899 Cannot send email with new iPad air. Works fine with old iPad and iPhone.

Cannot send email with new iPad air. Works fine with old iPad and iPhone. I have deleted account and reinstalled.

Thanks. I got the problem fixed. Spent time with the Apple folks and was kicked up to a senior advisor. It seems the problem was with my internet provider - Tmie Warner. Remember I could use the old ipad and the iphone to send mail. I checked all the specifics between the three units. It seems that TW is changing over from the RR.com to TWC.com. Since the new ipad air was just set up, it fell under the new TWC mail specifics.

I have a mid-2010 iMac and just purchased a 2TB TC, can't join existing wireless network with AC standard so attached to iMac via ethernet with TC wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. working fine with TM

I have a mid-2010 iMac and just purchased a 2TB TC, I just found out that it can't join existing wireless network with new AC standard so attached to iMac via ethernet with TC's wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. It is working fine with TM. My cheeper seagate drives etc kept crashing, so i didnt trust cheeper back up options anymore. Connected those drives to TM via firewire and could see the drives and access them.
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc. I connect to the internet via airport only and it is pretty fast. Getting over 50mbs downloads and over 30mbs uploads. Plus everything in my home it connected to my fios router, airport express for music streaming, two apple tvs, vuezone camer system. I really didn't want to monkey around too much with my system. But are there other options to connect the new TC. Can't find info anywhere for this and called apple who gave me the info above. after hanging up, i see that i cant access my TC and I am wondering if i would have to reset it to turn wifi on again to make changes to the drive, turn off blinking light or repair it in disk utility if it should become corrupted.
For other with similar issues i did solve some other problems: when i connected it to my ethernet port on my iMac wifi stopped working. Found that I had to turn off the ethernet in the system>network screen, but then TM didn't see the TC so i restarted after changes and then it saw it.
Now a rant. I can't believe in this wireless age that Apple would make a product that cant join a wireless net work. The apple rep said i could return it and look for the previous TC that would join an existing wireless network. Are we going backwards?
Thanks!

Ok... it is getting a bit clearer but there are still some questions.
I connect to the internet via airport only and it is pretty fast.
I was assuming airport in this statement in your first post meant the TC or the Express.. but I now realise we are still in the mass confusion stage where apple calls everything wireless an airport. So what you mean is the airport internal card of the computer??
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc.
I think this is mistaken.
Putting the TC in bridge mode plugged into your FIOS will not slow the network.. nor will it cause mail or port issues.. in bridge the TC is just a fancy WAP and switch plus the network hard drive.
If the computer is close it will be faster than the FIOS.
You can run both wireless networks with different names.. so it is clear which is which. But you can also setup roaming so the computers themselves pick which is the best wireless.
I tried extending the wireless net work and tried joining wireless network, but the TC kept crashing and I had to keep resetting the TC. the Apple support person said these, extend wireless network and joint wireless network, are no longer a connection option with the new TC because of the new AC protocol.
Thanks again!
You cannot extend to a non-apple wireless router.
You cannot use join a wireless network because when you do the ethernet ports will be cut off.
But that has not changed.. I don't think Apple support is correct.. there has been no change with the AC model.. it is simply a fact that apple routers do not work in join wireless mode other than as a dumb client. The same applies to AC as to the earlier version.. but I have asked another person to check this.
Join in the express is the only apple router that still allows an ethernet connection.
For now you best use of the TC is bridged to the FIOS. Wireless you can sort out between several options.

If you have records that show that you've taken your MacBook Pro in for a year to fix the machine, I would escalate the problem to Apple Customer Relations - unfortunately I don't have a number for Spain.
It would only seem logical to me that if you've been trying to have the machine repaired during the time that the 'recall' was in effect that you should be eligible for a new logic board. But only customer relations will be able to make that call.
Good luck - take the issue as high up the food chain as you can and see what happens.

HT1296 Is there any way I can transfer the music from my ipod touch to my computer without having to pay for it? Itunes worked fine with my ipod on my old laptop. I am not willing to risk losing all of the music on my ipod to update to the newest iOS.

I really don't want to lose all of the music I have on my ipod touch. It worked fine with my ipod and my old laptop but I got a new laptop and now it doesn't want to sync anything except purchases I made on the ipod and everything that was in the cloud. The rest of the music on my ipod is from old CDs and I am away from home. I would greatly appreciate it if someone could give me some advice. I also don't really want to pay for a download that moves the music into itunes so if anything is free and safe that would be great or if there is a way to do it manually. Again thanks to anyone who has advice to share.

You would have to purchase a 3rd party program ( not supported by Apple).
The ipod is not a storage/backup device.
Copy everything from the old computer or your backup copy of your old computer.

I am trying to connect to my Wifi Network. It is a Galaxy Nexus. I am trying to connect to this Hotspot. I have an iMac that works fine with my network but for some reason with this computer I cannot connect.

So far I have pulled the system configuration file, I have reset safari, I deleted all old passwords from the wifi network in Keychain I restarted both devices. I am at the end here and I cannot get it to work I have an iMac that works fine with my network but for some reason this computer will not connect. It is system wide specifically to my personal hotspot. I can connect fine to any other network (wifi) but just not mine. I have not changed any wifi settings. I have been trying to figure this out. I have a MacBook Pro Late 2006 model running Lion (10.7.5) So any ideas anyone? Please help!

12. At a WiFi hotspot, you can't get connected. The most frequent reason is the login screen for the WiFi hotspot is only able to be connected with a single type of browser. If Safari doesn't work, try Firefox, Chrome, Omniweb, or Opera.

How to register a PDF Viewer application to work fine with IE

(Working on Windows 7 Pro x64 / IE 8)
I've developped my own PDF minimalist reader application (to run on kiosk PCs) and I cannot make it work fine with IE. Every time i try to follow a pdf file link in a web page, IE ask me if I want to open or to save the file. working on kiosk PCs, i don't
want the final users to be able to click "Save" in order to prevent them from browsing drives !
When using Adobe Reader on the PC, clicking a pdf link results in the file opened automatically in Adobe Reader.
Here is what I've added to the registry :
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.pdf]
@="PCLSPDFViewer.Document"
"Content Type"="application/pdf"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.pdf\OpenWithProgids]

What did I missed ?

Hi
Chris RENAUD 768,
First of all the PDF files should be set to be read by the application you developed by default.
To set the default program:
Control panel \Programs \Default Programs \Associate a file or protocol with a program
In IE8 There used to be a key called HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\AttachmentExecute\{0002DF01-0000-0000-C000-000000000046} which stored the File Types that could either
Auto-Open or not. We can create a .bat file to automatically add a value here to achieve the goal.
The code is as following:
@ECHO OFF
reg query HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\AttachmentExecute\{0002DF01-0000-0000-C000-000000000046}
if "%ERRORLEVEL%" EQU "1" (
reg add "HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\AttachmentExecute\{0002DF01-0000-0000-C000-000000000046}" /f /v "PDF.File" /t REG_NONE
Note: Please Back up the registry before you modified the registry and delete the key {0002DF01-0000-0000-C000-000000000046} if it has existed in the registry before you ran the .bat file.
Best regards

Printopia is another option but be aware that since these solutions effectively act as a print server and AirPrint receiver, they require a computer to be running on the same WiFi network.
Canon also has a couple of apps in the App Store that might facilitate this on non-AirPrint printers. Check out...
