The remote sound of the egg ache, this time with the Bluetooth try

The previous article, "Using Jack to pass sound between PCs in Windows", is about the transfer of sound between Windows--windows. effect, the wireless connection uses to feel the sound distortion often appears; Wired connection does not have this problem. The alpha is also on a USB sound card, and then with headphones to listen. Long time is not accustomed to headphones, feel or open speakers good. But lazy cancer, poor cancer attack, do not want to come out to buy a pair of speakers, then seek other solutions, the last time Jack also installed, or feel the sound quality is not good (1 minutes of a jump frame you can endure? ), while the delay is generally not aware of the problem is not felt, but play CS test a bit, or is very obvious, the mouse attached to the click, the sound of a gun two gun look like ...

Bluetooth that is not reconciled to Ah, that this time to engage.

The first thing to be sure is that Bluetooth has an audio protocol, that is, the sound can be transmitted via Bluetooth. A notable example is the in-car music player, which allows music to be played in the car's stereo via the Bluetooth protocol. I think that since the computer function so rich, why not even a function of this? And on the Y450 above, through the official website to download the driver can be connected to the mobile phone, including calls can be forwarded! It is the computer that dials the phone and then calls it.

So I first checked, the key word is profile, but there is no useful things, but searched the Intel forum someone complained that the Intel Bluetooth wireless module does not have this profile problem: https://communities.intel.com/ Thread/45097?tstart=0

Well, I met the same as they said!

On the 37 floor, onlookers arrived at the solution: go to Asus's website under Atheros's network card driver (installing the Qualcomm Atheros BT Driver Suite) to see that some may appear incompatible, but I do not use this Bluetooth for a time, I don't think I can feel it.

That's natural to go down, although surface comes with is Marvell Bluetooth (pit Dad's Marvell said that FM radio!! However, I can also start after the installation, that is, configuration a bit of a problem. Because when alpha and surface were paired, surface was the simplest and most useless feature, so I needed to re-remove the previous pairing. I have repeatedly restarted several times, because found that the deletion is not complete: alpha is no problem, there are three places on surface: Modernui settings in the PC and device Bluetooth to delete, Device Manager to delete, The window for the device and printer is also deleted (I remember to delete one, possibly because the relationship was broken by reinstalling another Bluetooth driver)

After deletion, re-pairing added, added successfully. Alpha above the trumpet can see the optional USB out sound, or HDMI, or Bluetooth. However, it is not possible to output, manually connect from the Alpha sound option, and a sound is dropped. The reason is that the pair is paired but there is no steady connection and of course the sound cannot be transmitted. So how do you keep the two of them connected?

So look at surface:

When I first hit the driver and paired with no sound options, it may be that I restarted and re-paired before the appearance, then the right to connect a little bit (the picture is the status I have connected)

Tried, the sound effect is obviously better than the wireless transmission of Jack, but there will still be a delay problem. Subjectively, this delay is slightly larger than Jack's, but with ease in mind, the Bluetooth connection is a better solution than the following:

	delay	sound quality	easy to deploy Degree	other
Bluetooth Connection	large (Ying Sha one shot more)	good	just a silent Audio receiving end of the installation program, if the use of Atheros Bluetooth so that comes with these things, do not need to install additional.	Bluetooth is also cross-platform, but the one that has this profile has to be required to accept the sound at the end of Windows
Connection	relatively large (Ying Sha one shot)	occasional stutter, Pitch-shifting, such as drop-frame		jack cross-platform, although I did not use it successfully on the Raspberry Pi

Well, it's been a long day and it's been a toss-up. You may need to run AVRemoteControl.exe to make a voice connection (the default system does not boot this thing)
