Anyone know if FreeBSD drivers work with the SPDIF on these boards? "Live" card: SB0060 drive: SB0010C "Audigy" card: SB0090 drive: SB0010D There seem to have been various card model numbers in these Live/Audigy series (SB* / CT*) that have SPDIF inputs. Some cards show spdif_io pin headers on the cards (ebay pics) vs. an external cable to an external "drive". They're low cost so if driver support is there they would do fine. > On Tue, Dec 17, 2013 at 8:41 AM, Tom wrote: Send relevant stuff to the list, not me. > Not to crimp your plan, but there aren't many cheap consumer cards out > there with coaxial digital in. > > There are however masses of very cheap cards based on CMedia CMI8738 > with optical SPDIF in/out, for instance this one is ~ $10 > > http://www.ebuyer.com/239251-xenta-8-channel-pci-soundcard-with-spdif-and-cable-included-n-cmi8768-8ch > > You would then need to add a coax -> optical adapter, which should > cost another $10-20: > > http://www.amazon.co.uk/Cable-Mountain-Optical-TOSlink-Converter/dp/B001U7ERU6 > > I would imagine the next step up is a prosumer card, so hundreds of dollars. > > I would use ffmpeg to record: > > ffmpeg -f oss -i /dev/dspN out.flac > > You can do it step by step (record to wav, compress with flac), but > ffmpeg can do it in one step.
