John is having trouble chrome casting with an app called Hoopla. Leo says that it's likely a rights issue, and Hoopla is preventing it on the Chromecast, but works with the iPad. Hoopla has apps for Roku and Apple TV, and they work more consistently. Leo's guessing it's a problem with Hoopla and poor Chromecast implementation.
Greg has a Samsung laptop computer. He had to reinstall Windows 8.1 and wants to upgrade to Windows 10. But his touchpad isn't working, even though Windows says it does. Leo says that he suggests using the actual drivers from the manufacturer. Often they will be different from the Windows driver and will be designed for that model. Chances are, it's a Synaptic touchpad. If that doesn't work, then maybe the touchpad is broken or the cable is loose. Also, the chatroom says that there is a function key, it could be F9, that will turn off the trackpad.
Eileen bought a Bose sound system, which is connected to an optical splitter, so they can use her headphones too. But now the headphones won't work after a power surge. Leo says it's possible that the power surge fried the optical splitter. She should check if the headphones work with her TV (she may need to change her audio settings in the TV). It may also be possible that the settings changed in her TV, so she should look in there and see what it's offering. She may need to reset it to PCM unencoded audio or something similar. She should just try different settings.
Gary has an iMac, and there's a large percentage of JPGs he can't preview. What is that all about? Leo says if the dimensions read "0" by "0", then the Mac thinks that the files are damaged and need to be repaired, even though Gary can read them on a PC. He should try opening them in Preview first. If he can read them there, then he can export them. Gary can also open them in Picasa, and so Leo suggests exporting them out from there. That can fix them and the Mac apps should be able to open them from there.
Mike has a CD player with a tray that's jammed up. Leo says it's likely a titled CD that's blocked it and it's jammed. It may also be a torn table that has unglued itself and is gumming up the works. There may be a tiny hole that he can use a paperclip to free up the mechanism. Outside of that, he'll have to take it apart.
Barry's Bluetooth connection in his Infinity keeps dropping his iPhones when he's listening to Amazon music. Leo says that Bluetooth is really finicky, but it's all we've got. It shouldn't happen, but chances are, the problem is on Infinity's end and not Apple's. It could also be an issue with Amazon Music. He should try using iTunes and see if the problem is repeated. He should also check his app settings that could change the behavior. Maybe the app thinks he's getting a call and it's "ducking" the audio.
Ron bought a Western Digital Passport USB hard drive and he's having issues with it. Ron can see it in the device manager, but he can't access it on the computer. Leo says that a USB connected drive only means the computer can see the device. Doesn't mean it can read it. Drives do die, and sometimes they die sooner rather than later. That's why Leo recommend SSD drives for the main drive and a spinning drive for data. It sounds like his drive has simply died.
Brett just updated to OSX Mojave and hangs up on the login screen. Leo says clearing the PRAM or parameter ram can sometimes solve issues like this. Also, reboot with CMD R and that will enable you to reinstall the OS. Maybe it wasn't updated properly. If that doesn't work, Leo recommends making an appointment at the Genius Bar in the Apple Store.
Chatroom says to boot into safe mode, press and hold the shift key, and it will install the absolute minimum. If it works OK after that, then there's an app that isn't compatible that's hanging things up.
Shelly has Windows 10 and Microsoft EDGE, but she's having issues with her internet access. The website pages keep timing out. Leo says that antivirus software like Trend Micro may be working too zealously to protect you. Leo recommends only using Microsoft Defender on Windows 10. So try disabling Trend Micro or removing it and see if that helps. Check to see if other devices can get online, like your mobile phone. If you can, then it's a Windows issue. If not, then you're not connected at all. Are you sure you have connected your computer to your modem?
