I have been asked to raise a new thread for this discussion, so here goes:
I presently have a Beresford DAC strapped to the back of the TV with its two optical inputs driven by 1.A Chromecast Audio dongle receiving via Castbridge 2. A TV which has a Chromecast Video Dongle attached - this dongle is also recognised by Castbridge and audio may be streamed by that route. LMS sits on a old PC and works well enough though a Raspberry Pi would use less power! The old Beresford DAC is able to drive the amplifier and speakers (when switched on) and, with a separate volume control, drive headphones, so I have a setup that suits my needs well. I have seen the HIFIBERRY DIGI+ I/O advertised https://www.hifiberry.com/shop/board...berry-digi-io/ and I wonder if a Raspberry Pi with this hat and PiCorePlayer would allow me to achieve the same ends as above. Is it possible to use the I/O board for TV sound loopthrough? Would PiCorePlayer control the hat effectively for that purpose? I note the latest PiCorePlayer has graphical control of ALSA mixer, and that gives me hope. Deep modification of the underlying Linux would be beyond me. If this were possible a passive splitter on the analogue output of the HiFiBerry DAC would allow me to drive both the Loudspeaker Amp and a new Headphone amp with independent control. Is this a sensible approach as I look to replace ageing hardware? What other options might I have? A new external DAC with HIFIBERRY DIGI+ STANDARD https://www.hifiberry.com/shop/board...ndard-version/ would be one. I note some say taking the digital stream out from the Raspberry Pi by USB is not such a good option for sound quality. It must be a common need to merge TV sound into a quality lounge audio system.

That architecture changed with the Pi4, where the USB ports have a dedicated bus. I think now its accepted that with the pi4 architecture there is good quality sound from a USB external DAC. That has certainly been my experience. If I understand your requirements correctly, I would recommend something like a Topping E30 DAC https://www.amazon.co.uk/TOPPING-E30...ps%2C46&sr=8-3. You can connect your Pi to the USB input and your TV to the optical input. I use an E30 in this way and also have a CD player connected to the Coaxial input and am very happy with the sound quality. And Startibackfast In my experience there is no issue with the sound quality using USB into an external DAC from a Pi3B. I am not using the ethernet port though. And Man in a van: Hi Brian, good to see you posting again. I hope the old hip is well I think this is a no-brainer and should be done. With regard to the set-up, I think this might benefit from another thread as there are innumerable possibilities and they are are really, I feel, outside the intended scope of this thread. And my final word before moving thread: Thanks for your comments, all. The Topping D30 was in my sights. If the USB audio from a P4 is fine I have another option. In Southampton I run an old Beresford 7510 DAC which has no USB input, but I Nicosia I have a later 7520 which does. I could swap them over - when I get to travel! The other option is just to use a Raspberry Pi (hatless) as a server and park it next to the Router. I have enough receivers to go round! But from what I read, no matter what the final solution, the purchase of a P4 may be a good idea. and And it has just occurred to me that I have an Apple in-line DAC which is extreme well reviewed and costs £9 https://www.apple.com/uk/shop/product/MU7E2ZM/A/usb-c-to-35mm-headphone-jack-adapter There is a very easy solution. As suggested I will start a new thread. Brian In UK: Chromecast Audio Dongle and Chromecast Video Dongle attached to TV - Beresford DAC - Quad 77 Integrated Amp - AVI Neutron 4 Speakers - Sennheiser HD25 Headphones. Boom in Bedroom. In Nicosia: Delete Quad 77 and Neutron 4 and insert Quad 405-2 and MB Quart 980s ------------------------------------------------------------------------ Labarum's Profile: http://forums.slimdevices.com/member.php?userid=19963 View this thread: http://forums.slimdevices.com/showthread.php?t=115723
