看别的用户讨论 amlogic 盒子跑 linux:
Running Kodi Krypton (Google Play version) on Minix Android OS, 16-bit/44.1KHz audio files are upsampled to 16-bit/48KHz and all hi-res audio files are downsampled to 16-bit/48KHz over S/PDIF digital optical output (TOSLINK).
Running LibreELEC from SD card, all audio files - 16-bit/44.1KHz, 16-bit/48KHz, 24-bit/88.2KHz and 24-bit/96KHz - aren't resampled over S/PDIF digital optical output (TOSLINK).
The only problem is 24-bit/192KHz audio files aren't played, no sound at all over S/PDIF digital optical output. I don't know why, I don't know if it's hardware or software related. As far as I know TOSLINK is capable to output up to 24-bit/192KHz. I'm still looking to identify the problem ...
如果要求不高,100 元买个 Q5,跑 LibreElec,就可以听了,安卓版本有 SRC,Linux 版本关闭重采样了,LibreElec 早期版本也有,记得前二年用户反映了很多
至于误差问题,我觉得,我们没有仪器作测试,还是不好说对结果影响有多大
PC 上面,10 年前的 ALC883 就支持 44.1/48KHZ SPDIF 输出了,至于用了几个晶振,倒是没有研究过主板 |
