Gary Wintleson, I blow smoke upon you.

I'm posting in this forum as opposed to Inspect Your Gadgets because I feel like this might be a better fit here, but if it isn't, please move it over there if it's a problem.

I have a pretty decent surround sound system and keeping it plugged into my laptop via HDMI is getting a little annoying with the whole cord being attached and all coupled with the need to move with my laptop around my apartment. It sucks when I need to move away from the system with my laptop and I'm limited to 10 foot of tense cord. I'm trying to find a way around this. I've see some "wireless HDMI," peripherals like this one http://amzn.com/B009E6R89C but they're really pricey from what I'm seeing. That's pretty much what I need but I'm wondering if there are alternatives or simpler solutions. I don't really care about streaming the video portion, but that would definitely be a plus.

I'd ideally like to stream my laptop's audio to my surround sound system wirelessly. I was looking into Chromecast, but I don't think there's a way to output all of my computer's audio to that. What are my options for doing this without shelling out $200 and having something clunky attached to my laptop? I'd be willing to drop $100 or so on it though.

Thanks for any and all help!

I believe Apple TVs are capable of streaming lossless audio.

Are they capable of simply receiving all of my computer's audio output? From system sounds to whatever I have playing on whatever application? From what I'm reading it sounds like it's pretty heavily reliant on iTunes.

What's the exact model of the receiver, and does your laptop have Bluetooth? There are about a half dozen ways to go about this, many of them cheaper than a wireless HDMI transceiver. Also, are you willing to do a little DIY effort, like setting up a Raspberry Pi?

I'm not near my system at the moment so I don't know the exact model. I know it doesn't have bluetooth though. My laptop however, does have bluetooth. And yeah definitely into DIY stuff, Pi's have been something on my radar for a while, just never had any solid ideas for putting one to use to jump on one.

Well, then, get a Raspberry Pi and make it an Airplay receiver.

If that seems like too much effort, then Monoprice will sell you a Bluetooth audio receiver with stereo miniplug out for $20.

You're looking at some pretty serious quality degradation with anything Bluetooth.

This isn't true, and hasn't been for years.

http://en.wikipedia.org/wiki/List_o...file_.28A2DP.29

You just have to make sure the Bluetooth devices you use support the codec you want to use.

Here's how to check what your laptop supports:



If it says A2DP, you're good. Here's a cheap bluetooth receiver that supports A2DP, but doesn't list any codecs:
http://www.monoprice.com/Product?c_...#specifications

Here's one that specifically says it supports APT-X (one of the highest quality codecs bluetooth can support):
http://www.amazon.com/Yamaha-YBA-11...+audio+receiver

Edit: The Yamaha requires a coax audio input on your receiver. You probably have this, but you should check (It's probably orange and near the TOSLINK inputs, if any).



Also, you need a way to power a USB port. Your receiver or TV probably has this. If not, you can use a USB A wall plug adapter.
http://www.amazon.com/Powergen-2-4-...SB+wall+adapter

Double Edit:

If you go with the Yamaha, make sure your laptop's bluetooth supports APT-X. If it doesn't, get this, too:

I use this setup to stream any specific program to my Raspberry Pi but this is under Linux. I'm sure you can do something under DLNA/UPnP with Windows. It has something like a 10 second delay between initiating a change in the stream before it's heard on the stereo.

Even though A2DP is an improvement, it remains a waste of a nice stereo system to be feeding it compressed audio over bluetooth.

A2DP supports the most common audio codecs (MPEG-1, MPEG-2, AAC), which is more than likely what your music is stored as in the first place (Unless you're one of those FLAC/ALAC wierdos. Don't be a FLAC/ALAC wierdo). If you need higher quality than that, I specifically posted devices that support aptX. Stop spreading misinformation based on what Bluetooth used to be like 5 years ago.

I'm looking to do the same thing as the OP. I've skimmed a few of the Raspberri pi articles linked here, but I'm missing how the physical setup goes. Does the receiver need to support wireless directly?

I'm picturing something like this: Laptop -> WiFi/BluTooth -> Raspberri Pi -> Receiver via HDMI/Optical. Is that what these setups accomplish?

Yes, it is, except the RPi doesn't have optical audio by itself. So it's HDMI off the Pi, and if you need TOSLINK or whatnot you need a compatible USB audio device or a splitter that will peel the audio off of HDMI.

I got BluTooth streaming working on a raspberry pi using this tutorial. However, the audio's delayed about a second, making it unusable for videos. Is there a better solution? Is this inherent to BT? What about WIFI?
