I finally got round to testing my new HDMI cable with my laptop yesterday, and was most impressed that it was very much plug-and-play. Linux Mint managed to detect the TV, and automatically set resolution & “stretch” the desktop to it, all within 2 seconds without me having to do anything. However, it didn’t take the audio - that was still left through the laptop speakers (come to think of it, I didn’t actually turn the TV up, so it could be my failing there :-[)
Anyone, this post is still valid because I want to get Bluetooth audio working. We have a soundbar that has Bluetooth input, and ideally I’d like to stream the audio from laptop to soundbar whilst the HDMI cable is inserted into the TV. I went into the “Bluetooth settings” in Mint, but it said “no Bluetooth devices detected”. Windows would beg to differ. I reckon this is a “lack of libraries” issue, but I’m pretty lost when it comes to Bluetooth. :
Can I get some basic stuff that I can try to get Bluetooth recognised?
I’ll have to check that tonight (I assume I install it if it’s not). Is there associated config that needs doing with that?
It doesn’t detect any Bluetooth devices at all (according to the GUI), I don’t even get as far attempting discovery (it’s like it’s hard/soft blocked, but I assume that doesn’t exist with Bluetooth). There is no Bluetooth key/switch on the laptop
I can’t be 100% sure I’ve ever had Bluetooth working on here, but there are Windows drivers for the Acer Aspire 5755G on their website for 2 Bluetooth adaptors (I’ve tried both to no avail). I’ve got a bluetooth folder, with received files in it, but I may well have copied them on from somewhere else. Damn my memory!
I think we’ve had a good stab at this, I guess I’ll have to settle for a good old 3.5mm cable. Shame it’s come to that in 2015, but I guess that’s what you get for buying a budget laptop
Yeah they did that laptop with
a) a Broadcom adapter
b) an Atheros adapter
c) no bluetooth adapter
If the Windows device manager doesn’t list anything, you probably have the one without a bluetooth adapter fitted …
(I’m pretty sure they used an Atheros AR9485WB-EG wireless/bluetooth adapter when they had bluetooth … but yours has the Atheros AR9287)
You could always get a USB bluetooth adapter or buy any Half mini PCIe wireless/bluetooth adapter and fit it internally.
Thanks Mark, confirmed my suspicions (I couldn’t derive the conclusion from the data I was looking at)
I think I’ll look towards one of the minature USB ones (like the kind you get with wireless mice), how can I be sure to get a Linux compatible one. More than that though - do you think there would be noticeable lag between picture and sound, if I fired the sound via Bluetooth rather than 3.5mm audio cable?
Thanks for the heads up
Any chance it’s been patched upstream by now? Launchpad suggests no, which is a bit disappointing
I don’t know anything about bluetooth audio implementation - is the A2DP standard a universal bluetooth audio protocol, or is it some fancy new, not-generally-supported protocol, and there is a standard lo-fi protocol to fall back to? (a bit like open-source graphics drivers, if the closed-source don’t work/aren’t available)
Ah, I can’t find the spec on my soundbar to see if it supports it anyway, so I might be in luck (as in, if it doesn’t support A2LP, but neither does the adaptor, it’ll still work). I guess the quality will be crap though.
I’ll bite the bullet and buy it tonight, only one way to find out!
