Continuing the theme of network audio player streamers, started in the review Budget network media player with decent sound based on Raspberry, I want to talk about another platform for this, which has some advantages. The product was provided for writing a review by the store.
Audio enthusiasts have long regarded this platform as the only one (of single board computers) capable of realizing hi-fi level audio extraction. Review published in accordance with clause 18 of the Rules This is the BeagleBone Black Rev C from Texas Instruments.
This creates the possibility of building a platform for a sufficiently high-quality sound source, which at the same time has extended
network, Internet capabilities, as well as flexibility in settings, selection of software and integration with external services. In this regard, it is strange that there are so few ready-made solutions for this platform. Only enthusiast products or independent connection to the I2S bus, which without certain manipulations can only be implemented with certain restrictions (for example, when playing DSD). At the same time, it is not possible to apply an external MasterClock with the processor operating in Slave mode. I’ll try to build something on this base myself.

BeagleBone Black as a basis for creating a network hi-fi player

How to get it – I will write a review later. Dream!
BeagleBone Black cannot boast of processor power, and this is not required when playing audio, but the board has its own 48kHz generator that supplies frequency to the HDMI TDA19988 processor, and the AM3358 processor is able to work in Slave mode, accepting external clock to only the missing 44.1kHz or both carrier frequencies, delivering the https://jiji.com.gh/251-makeup-brushes/professional much-needed bitperfect for audiophiles. It is understandable, there are no high-precision oscillators in the processor and on the board, the frequencies are formed by recalculation. Raspberry, the player on which I described earlier, in most cases (except for the one I described :)) does not provide such an opportunity. It is not surprising that enthusiasts have long paid attention to this platform, discussing the construction of devices based on BeagleBone on specialized forums, for example, here, as well as creating additional audiophile feng shui in the form of a galvanic isolation of a computer from an audio interface, the use of external audiophile frequency generators, advanced food, etc. The reason is that the Broadcom BCM2837B0 processor outputs a frequency to the I2S bus, the quality of which leaves much to be desired for hi-fi audio playback purposes, as they say.
