    james_bond reacted to WereCatf in Loss of Bluetooth signal   
    Get a short USB extension-cable and try putting the Bluetooth-stick sideways on a table and see if the signal now works when lying down, but has issues when you're sitting up; if it does, that means your headset has kind of crappy, really directional antenna-setup.

    I use this adapter with my computer: link. I have no idea about compatibility with Linux but TP-Link support web page says it is not compatible. Regardless, my intuition says that this is only because they don't formally support Linux. A Canadian review on Amazon's webpage says that it worked automatically with Ubuntu.

    You don't mention where the adapter in your PC is. If it's e.g. in the back of the PC, that could reduce the range of it. For best results, you'd want to have line-of-sight, so using e.g. a USB extension-cable to bring the adapter to a spot where it has line-of-sight to your bed might help.

    I don't even know how to find that BT adapter but I would suggest spending $10 on a USB BT adapter. If range persists to be an issue then you can always get a USB extension cord and place the adapter in a better place where it will have less interference.

    Other than getting a new Bluetooth adapter, not really. Seems like a range issue. Bluetooth is not well known for having amazing reach.

    james_bond reacted to Mark Kaine in Is there any free reliable proxy service that I can use while torrenting ?   
    My ISP has a proxy server for free...
     
    However I just checked they're closing it soon... No idea why... ?
     
    But you could check if your isp has a service like that.
     
    As far I know the one from my isp was very reliable (DTAG)
     
    But now I'm just baffled they're closing it... Seems odd.

    james_bond reacted to soundrunner96 in Big problem !!! My LED TV has no HDMI ARC   
    I had a similar situation when I got an Atmos soundbar. If you plan to keep the TV for awhile I would suggest getting a soundbar that has an HDMI input on it.
     
    However, I have had issues with getting Atmos from my fire 4k stick to the soundar. Not an issue coming from my computer, but from what I've seen, the fire tv stick won't output Atmos from Amazon content unless it detects a 4k tv. Could be wrong but I haven't been able to get Atmos working on it yet.

    Honestly, I didn't check what TV you have, so I apologize for that.
     
    Buy a new TV.  Or get the Amazon Fire TV Cube, it has audio out.  Or maybe something like this:

    You need to either jury rig some aspect or get a TV that can handle the tech you're wanting to use.  I had to up my ante to a Roku Ultra w/ optical out for a similar reason.

    james_bond reacted to Kisai in Why do most of the wireless headphones use Bluetooth connectivity ?   
    Bluetooth is awful, and the primary reason for this is eWaste. If you have headphones that have proprietary radios, they won't play nice with other equipment ("this device will accept all interference, and may have degraded performance" type disclaimers) where as bluetooth devices will play nice with each other on the 2.4ghz band but WiFi won't. So if you're surrounded by 2.4Ghz radios (Eg wireless keyboards and mice) already, bluetooth will probably have limited range, and WiFi will probably not operate at it's peak performance. 
     
    Most of the rubbish tier equipment out there doesn't want to pay for bluetooth licencing, so they may still use a proprietary wireless solution, but the reality is that unless the headset has a external charging requirement that is also the wireless base station, which gives it an excuse to use it's own radios, it almost certainly costs more to produce those proprietary radios than it does to get off-the-shelf bluetooth parts from a third party.
     
    So what's most likely happened is that the cost for bluetooth radio parts has gone down (and really should cost half as much, as the headphones only need one half of the radio pair, where as proprietary solutions require two radios.) Which re-affirms the point that the "95% only use bluetooth" is probably because of cost. So a super high end headset/headphones may prefer it's proprietary radios to get more audio bandwidth, or a super-low end headset may be using proprietary radios based on older tech.
     
    Like to give you a base point here. The wireless headsets that are used in offices and call centers, are not bluetooth, they are DECT. The base station/charger's give you a fair amount of distance, can be conferenced with each other, and even support bluetooth devices like mobile phones, conventional telephone handset connections, and PC (skype/teams.) But the quality of these headsets are debatable, as DECT is a standard you may recognize as TDMA, but on the 1.9Ghz band (which sits next to the DPCS band for cell phones, and as such North American DECT can not be used outside North America, and European DECT devices can not be used here.) They do not support high quality audio profiles.
     
    But I digress, I think most people should not be using wireless headsets as putting wireless stuff near your head dangerous in the first place.

    All of the cancer scares about Bluetooth and cell phones in general are just BS!  This started happening when cell phones came out and there were worries about constant usage and brain cancer.  In the US, there are very good statistics on the number of brain cancers per year.  There has been a downward trend in occurrence with a huge increase (exponential) in cell phone use.  One might argue that cell phones protect you against getting brain cancer!😉

    james_bond reacted to LAwLz in Why do most of the wireless headphones use Bluetooth connectivity ?   
    Bluetooth uses the same spectrum as WiFi, but at lower power. It is literally the same signal (physically, how the chips interpret the signal is different). That's why it is possible to have Bluetooth/WiFi combo chips and antennas. 
    If WiFi isn't causing cancer (which is the scientific consensus) then Bluetooth isn't causing it either. 
     
    Your old headphones that used some proprietary RF signal probably operated in the same spectrum as Bluetooth and WiFi as well, so it is just as (un)likely to cause cancer as Bluetooth and WiFi.
    The reason why I believe your old headphones also used the same frequency as Bluetooth is because 2.4GHz (what WiFi and Bluetooth uses) is in the so called "unlicensed spectrum". Here is a list of stuff on Wikipedia that uses the 2.4GHz radio spectrum and here is a good article that explains why so much stuff uses that particular wavelength.

    Pretty much everything causes cancer. Or at least in does in California.
     
    Bluetooth uses the same band (at lower power) as 2.4 GHz wifi; no appreciable risk of cancer.

    short answer no
    (its on a UHF radio spectrum)
    there has been no solid evidence and these are pretty low power transmission compared to FM and AM

    Everyone and their dog (probably almost literally) supports Bluetooth, and recent revision have made Bluetooth good enough for the job. Lossless audio can even be transmitted, though both devices must support said lossless format.

    My only issue with bluetooth, is that if you buy a bluetooth dongle online, unless you pay the premium for a brand name, you're likely going to get scammed. I bought 3 bluetooth dongle for my PC in the last year. They all claimed to be BT 5.0. 
    All of them reported as either BT 4.0 or BT 4.1 in Windows.
     
     
    But yeah, like the others have said, because of how ubiquitous it is. Bluetooth connectivity is in pretty much everything these days. My brother's toaster and micro wave also have bluetooth in them. I'm not even joking.

    Newer bluetooth versions are probably much more energy efficient and can also give more quality (depending on codec). FM I would guess is susceptible to noise and other issues and probably more power hungry to both transmit and decode..

    Ubiquitous Bluetooth in cell phones (and to a lesser extent, laptops and consoles). It's also a fairly universal standard, instead of being locked to a certain brand's transmitter.

    Low power consumption, cheap to implement, every smartphone supports it...
     
    Edit:
    Keep in mind that basically all (couldn't think of one that doesn't) mobile devices use a single chip for Wi-Fi and Bluetooth.

    james_bond reacted to VoidX in Trying to understand the importance/role of AV Receivers   
    It's mostly down to what ecosystem you want to build. An AVR is typically a plug-and-play home theater, it just works, contains all features in low or mediocre quality, has integrated amplifiers, lots and lots of inputs, and is very easy to use. If you don't want to include a PC in your living room or theater, this is your only way (or a preprocessor + amplifiers, which is just an AVR in parts).
     
    The pros and cons of HTPCs with sound cards and dedicated home theater equipment are basically the same as for PCs and consoles:
     
    HTPC with sound card:
    Audio quality range: very bad to exceptional Only supports up to 8 channels, which is 7.1 for regular setups or 5.1.2 with hacks I make Supports every existing codec if you just update your player Ultra high resolution phase-perfect calibration Perfect delay and gain control for accurate spatial imaging Free (everyone has a PC), but your sound card might be very low quality, and amplifiers have to be bought for actual home theater speakers Not trivial to set up perfectly Dedicated preprocessors (including AVRs):
    Audio quality range: mediocre to very good Dolby Atmos, DTS:X, and Barco Auro support up to 16 valid and 35 virtual channels Limited codec support, for example, Vorbis is rarely, Opus (the most advanced known compression) is never supported in the home theater ecosystem Very poor calibrators with phase distortions and little to no methods of manually fixing it Delay and gain control is only for fixing serious issues Very poor price/value ratio, which gets worse the more advanced equipment you buy Plug'n'play The video differences are kind of the same story.

    I wanted to know the answer to this question for a long time.
     
    Almost all PC motherboards these days offer multichannel audio with no extra sound card needed.
     
    You can buy a speaker like this one >>> Click here and connect the three 3.5mm jacks to the rear of a PC and you get surround sound.
     
    Then why buy an expensive AV receiver ? I am just a newbie & know almost nothing about the subject so please educate me.

    *Only on TV or other dedicated apps. PC browsers and YT don't have surround. I feel like at least up until recently Hulu also didn't have surround, if it indeed does now.
     
    But otherwise, yeah games and movies are the only reliable source of surround, and a bunch of movies use it so poorly/minimally it may as well be stereo.

    I'm pretty sure a bunch actually broadcast DD which is encrypted into a stereo format. Could be wrong, but we used to have a 6.1 setup in the living room and got a lot of surround sound, though that could've been mostly the movies.
     
    When I was running a cheap logitech 2.1 and 5.1 for a total terrible 7.2 system it had surround sound in everything I tried. i.e. I never had any issues with anything. If there was an issue, it wasn't anything downloading a codec couldn't fix since that's all that's on AVRs doing the decoding anyways.
    In any case, the "high end" Logitech 5.1 seems okay, but upgrading to an actual AVR is a definite improvement and now I can play my PS4 or whatever else with 5.1 as well.

    You use a receiver when you want to have multiple sources outputting audio or video to one display or speaker system.
     
    For example plug in your receiver into a single TV and speaker system. And then plug your PC, consoles, etc. into your receiver.
