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.)

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...

linux - Extract/save a mail attachment using bash

Using normal bash tools (ie, built-ins or commonly-available command-line tools), is it possible, and how to extract/save attachments on emails? For example, say I have a nightly report which arrives via email but is a zip archive of several log files. I want to save all those zips into a backup directory. How would I accomplish that? Answer If you're aiming for portability, beware that there are several different versions of mail(1) and mailx(1) . There's a POSIX mailx command, but with very few requirements. And none of the implementations I have seem to parse attachments anyway. You might have the mpack package . Its munpack command saves all parts of a MIME message into separate files, then all you have to do is save the interesting parts and clean up the rest. There's also metamail . An equivalent of munpack is metamail -wy .

ubuntu - Why does my USB hdd returns SG_IO: bad/missing sense data?

I am able to boot and run commands from external USB hdd; the message in question appears for about 45 seconds then booting continues. GRUB2 is installed on internal HDD. When choosing to boot directly to /dev/sdb the message doesn't appear, however boot time is about the same as booting to internal HDD. /dev/sdb: Timing cached reads: 1018 MB in 2.00 seconds = 508.97 MB/sec Timing buffered disk reads: 80 MB in 3.03 seconds = 26.37 MB/sec pfeiffep@de:~$ sudo hdparm -i /dev/sdb /dev/sdb: SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 10 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 HDIO_GET_IDENTITY failed: Invalid argument Gparted correctly identifies the drive as SAMSUNG MP0402H. Any ideas how to remedy the HDIO & SG_IO messages?

Desktop reboots itself on sleep or hibernate

I have been using an ASUS M2NPV-VM motherboard for main home desktop workstation, operating Windows Vista x64. This computer has right from day one not been able to enter hibernate or standby; after Windows performs its final actions and brings the machine down, it would automatically revive itself for a reboot. Updating to the second latest BIOS (1201)has not helped (the latest BIOS revision would induce video refresh problems rendering it unusable). I have been reading related discussions on incidents similar to mine to no avail of a true workable solution. They appear to be more speculative guesses rather than actual knowledge on the inner workings of motherboard hardware. Does anybody have any electronic engineering experience on PC energy-saving standards to provide a more informed opinion how to go about getting this to work? More stories: this motherboard could not even reboot properly the first thing i used it. It was due to refresh rate of the onboard GPU, which had no influe...
