connector - Are there desktop 3.5mm jacks that can interface with smartphone TRRS headsets?



The TRRS jack is a recent modification of the 3.5mm audio connector which allows microphone data as well as control signals to be passed from the headset to the device.


However, this standard does not seem to be usable on 3.5mm jacks on desktop computer motherboards. On a number of tablet-notebooks, I have noticed that the 3.5mm jack works to control the playback of audio, but I have not ever had one of these headsets work on desktops as a headset device.


Are there any desktop based 3.5mm jacks that support the usage of Android/Apple headsets microphones/control signals?



Answer



Yes. Apple computers (Both Laptop and Desktops) for the last few years have been able to use iPhone standard (CTIA Standard LRGM TRRS) headsets, with remotes even, for audio in and out.


Apple Support: How to use Apple Earphones with Remote and Mic with your Mac



Which Apple computers work with the microphone and volume controls that are included with the Apple Earphones with Remote and Mic?


Any computer that displays "External microphone" in the System Profiler will work with the Apple Earphones with Remote and Mic. To confirm that External microphone is in your System Profiler, choose About This Mac from the Apple () menu and then click More Info. Select Audio (Built In) under the Hardware section.



Note, it's only supported in OSX, not Bootcamp/Windows, AFAIK.


Any computer with USB 3 Type-C connector could/should possibly support it as well.



The USB Type-C Cable and Connector Specification Revision 1.1 specifies a mapping from a USB Type-C jack to a 4-pole TRRS jack, for the use of headsets, and supports both CTIA and OMTP (YD/T 1885-2009) modes. See Audio Adapter Accessory Mode (Appendix A):


Analog audio headsets are supported by multiplexing four analog audio signals onto pins on the USB Type-C connector when in the Audio Adapter Accessory Mode. The four analog audio signals are the same as those used by a traditional 3.5 mm headset jack. This makes it possible to use existing analog headsets with a 3.5 mm to USB Type-C adapter. The audio adapter architecture allows for an audio peripheral to provide up to 500 mA back to the system for charging.



(Side note, many flavors of Linux now support TRRS headsets, if the hardware it's on support it as well.)

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
