Capturing digital audio stream from TV 2020-05-20 22:00:12 Hi there,Long time reader, first time questioner here.Basically, what I'm wanting to do is to stream a concert through my TV in 4K (for the best audio) and somehow route the audio to my computer so that I can capture/record it. My goal is to then use this audio to make my own album for future listening so that I don't have to always stream the full A/V concert. Your advice is needed!My TV is a 4K/UHD LG smart TV, and has digital optical output as well as HDMI ARC and the usual RCA connections. The A/V data stream is coming into the TV from an Apple TV 4K unit via HDMI.My computer is a Dell XPS 15 9560 and lists the following sound cards listed in Speccy: - Intel Display Audio - NVIDIA Virtual Audio Device (Wave Extensible) (WDM) - Realtek AudioAs far as the recording software goes, I had thought to use Audacity's 'record' function as it seems like a fairly straightforward setup.My intention is to see if I can capture the unbroken digital audio signal in the easiest way possible - but reading around on the different forums, unfortunately I could not see a way to do this. I understand that one complication is that the digital streams are encrypted (is this the case?) or have some form of DRM which prevents 'capturing' them digitally.I had a few ideas on where to begin in terms of the recording setup: - TV => HDMI ARC => Computer - TV => HDMI ARC => USB adaptor => Computer - TV => Digital optical cable => HDMI adaptor => Computer - TV => Digital optical cable => USB adaptor => Computer - TV => Digital coax cable => M-Audio Audiophile 2496 PCI Digital Audio Card => ? => ComputerI also know that there are external sound cards that can convert from digital to analogue, which could then feed into my computer - but my worry is about the fidelity loss in converting from digital to analogue to digital again. I'm happy to be corrected as to whether this is actually an issue. I've also suggested above using the M-Audio Audiophile 2496 PCI Digital Audio Card as it has digital pass through. But I appreciate that another card might be a better fit for what I'm trying to do here.Has anyone here had success with their own setup? Is there anything here I'm missing or which is technologically not possible due to incompatible parts of the path? Or is there something I'm not understanding about the way the digital transmission works?Any help or guidance appreciated. As are links to another post which offered a successful solution (as said above, I couldn't find anything over a number of google searches).With thanks in advance,Paul.
