The delay from USB DAC is a different problem when compare to Youtube type application. This is kind of technical but since the issues has been raised again, I'll try my best to explain the situation.
i5's USB DAC is implemented in Asynchronous mode. This has been well-accepted as the only acceptable option for high fidelity audio application. In fact USB Audio used to be rejected by the audio community and the Asynchronous USB was the game changing technology, all of sudden everyone wants Asynchronous USB in their digital audio chain.
So what exactly is Asynchronous USB DAC?
Understanding Digital Music -- USB Audio Transfer Method from Soundstage.
So please do not expect the audio output of an Asynchronous USB DAC will synchronize with its source (a compute in this case), the technology has purposely make them independent from each other, a buffer is added into the chain deliberately, and this will inevitably delay the audio signal output with reference to the source computer.
The delay will not be "improved" by future firmware, because this is a correct implementation of Asynchronous USB DAC.
Hey, i totally get that and i dont really mind at this point anymore.
the i5 does what its supposed to do and it does it great. ive never listened to any source which sounded as good although this is my first mid to hi-fi dap.
my question really only had the goal to know if my i5 has some other issue as ive discribed before and the only thing i wanted to know was if someone could connect his i5, play the video i posted and check if the delay is on par with mine, or if the delay for my i5 is somehow even bigger because of the crash i discribed.
i would really appreciate it if you could test that for me as i dont have any possibility to test another i5 myself.
its not about making any negative point as i really love this device.
i only would like to know if the delay im having is the same as everyone elses or if it goes even deeper because of the crash.
also if i put some video on the i5's internal memory it should play without a big delay as its not using any of this asynchronus mode right?
also i would like to give some feedback for tidal use if that may help in fixing the stuttering.
i use tidal in offline mode with all files on the i5 internal storage as i dont even have an sd card in it atm.
the stuttering seems to be depending on the songs/albums played.
there are some albums which i can listen to for hours without any stuttering and then there are some albums/songs which have stuttering almost every 10 secs.
one bad example would be "i can't stop (ekali tribute)" by flux pavilion. first i thought it maybe has to do with the number of songs in the album as this was released as a single but when listening to the album "toxicity" by system of a down i also have pretty much stuttering. i dont know about all the songs but i just retested it with "deer dance" and "jet pilot" and there was a relative large amount of stuttering (not close to as much as with i cant stop though, which seems to be the king of stuttering).
some positive examples are the album "anything goes" by klaypex and the album "warlord" by yung lean. i think "reanimation" by linkin park also worked farely well.
im thinking that maybe the songs which have more stuttering may have higher bitrates or something as i dont know why else it should change so drastically from song to song.
i didnt checked the specific files yet though but i plan on doing some comparison between files which work great and those which dont work as good and check if they vary strongly in size/playtime as i dont think one can directly see the bitrate from the file details.
another thought i had was that maybe something with the download went wrong but i had done a factory reset inbetween and downloaded all songs again with similar results with the same songs which should throw that theory out.
i hope that this may help in some way!
