I have well documented it in this forum already. The problem is that any search input results in a list of all tracks relating to the input and play of a list of all those track begins when one select to the view the list. Eg type in ALLMAN, then, for me 138 tracks appear, and start playing on selection, of Allman Brothers Band, this is entirely unsatisfactory. As has been requested many times, the need would be to display a LIST OF ALBUMS appertaining to the search then one can dig deeper into the albums and/or play one. This has been fixed in the Fiio X7ii thus it is a known issue for Fiio and I am surprised you have to ask what the problem is when it's an ongoing request for the M6 and M9.
