I have been using an Apple TV 3 as a AirPlay receiver through Optical (Toslink) long before trying the A1392 and have never had any issues with the SMSL SU-8 V2 DAC to this day (even after a recent "auto" firmware update). (Apparently there were security updates in the latest AirPlay 2 supporting firmware, so I just left it on that firmware since all of the available ones are broken with Optical anyway) On the latest firmware the analog 3.5mm output (using the A1392's built-in DAC) works absolutely fine. I hoped the A1392 could be rolled back to this “golden” firmware, but it had already been updated to the latest (which supports AirPlay 2) and among the "roll-back" options the old firmware without the broken Optical output was no longer an option.Īt this point I tried all available roll-back options and they all had the same issue with the digital output. I cannot recall the firmware number exactly, but a select few past firmware options had flawless Optical output. Most likely extremely high amounts of jitter, which caused the DAC to have a tough time keeping the signal.Īfter extensive searching online, many had the same experience and it seems that Apple had "broken" the Optical (Mini-Toslink) output of the A1392 with firmware updates. Using it connected to the SMSL SU-8 V2 DAC via Toslink resulted in audio which was constantly interrupted and with glitchy artefacts. Just to report my experience with using the Mini-Toslink output on the A1392 Airport Express.Ī while ago I bought the A1392 second hand to use as a AirPlay receiver connected to a DAC and the results were pretty terrible. Since I doubt they'll do that (7.8.1 was released in 2019 for a discontinued product), hopefully that Belkin adapter will perform better than this. It'd be really great if Apple released a firmware fix for this. With this downgrade, you lose Airplay 2 for synced multi-room playback, and it seems Airplay 1 is much more prone to dropping the stream if you pause the music for a minute or so, and I have to turn the the volume every time I connect with Airplay 1 since it never remembers that I have the digital volume at 100%. Reverting back to firmware 7.6.9 and Airplay 1, audio is crystal clear. If it were clipping, I'd have expected the digital volume control to fix it, but even dropping it very low, and turning up my headphone amp, I still hear the static. Inspecting these recordings in Audacity, I don't see the tell-tale signs of clipping, even in the 7.8.1 release, but you can definitely hear static. QuickTime 7.0 included the H.264/MPEG-4 AVC codec which supported HD videos, Core Audio for high resolution sound and updated the UI.Here is the clip from iTunes 12.11.0.26 on Windows 10, far less crackling, but it's still there QuickTime 6.0 supported MPEG-4 playback and iTunes. QuickTime 4.0 available for Mac and Windows was the first to support streaming videos from the web and mp3 playback. QuickTime 2.0 was released in 1994 and was the only version during its history to not be freeware it included support to play music tracks and with the later release of 2.1 Apple made the software free again. Later on in 1992 QuickTime was contracted to allow for compatibility with the Windows OS but with limited features. QuickTime 1.0 was originally released with just three codecs they were suited to live action video, cartoon-type graphics and 8-bit images. QuickTime is available for both Mac and Windows.Īpple released QuickTime in 1991 and it was a technological breakthrough at the time, delivering a program that could play videos on a personal computer. QuickTime has moved on from being a simple video clip player to include more advanced features such us the ability to create HD videos, convert media into other formats and watch streamed videos via the player or browser. which plays a variety of different formats of digital video, pictures and audio.
