Hi everyone,
i'm following this great forum for a long time. I've never registered because i've always found an answer to my questions here but not this time
I bought the dx50 one year ago with the pre-installed firmware 1.50 and I was happy with that since i tried to use it as a USB DAC with ubuntu/xubuntu. It worked perfectly with 1.50/win7 but I've read that the older firm doesn't work with linux (until1.9.3) so today i've upgraded my dx50 with the last 1.9.4. The process ended OK, from the update to the factory reset, etc etc, i'm listening my dx50 right now (it has a different sound compared to 1.50. It seems "rounder", less "raw": I really liked how 1.50 sounded, I was really satisfied but this 1.9.4 seems to be a step forward to me, even the instrument separation seems better)
Here my doubts/problems:
1 USB MODE: STORAGE: everything works fine with win7 (really?? strange
), the problem is with the pc with ubuntu 15.10 installed: it's not able to recognize the dx50. Instead the older pc with xubuntu LTS 14.04 is ok (even if it's not able to read the sandisk microsd 64gb in it but it's not that problem).
2 USB MODE: DAC USB: again, win7 is ok (?? unbelievable), after the driver installation I select "DAC (Windows)" in the dx50 and everything is fine.
Instead, I'm not able to select "DAC (Linux/Mac)" in the dx50 so i'm not able to try it as a DAC, even with xubuntu. When I press "DAC (Linux/Mac)" the option is highlighted but there's no way to select it, the flag always goes back to the top to "Storage". Is anyone having the same issue? Am I doing something wrong?
Last question: if I want to try some older firmwares to see if they work can I use the same upgrade instruction to "downgrade" to older firmware? (for example: can I install the old 1.9.3 over the 1.9.4 without issues following the upgrade instructions?) if I want to try a modded firmware (like SU from dmitri based on the old 1.6) is it possible to install over a newer version without problems? i've read about Rockbox but i don't want to use it, it uses a dual boot modded firm and I don't want to get things too complicated
many thanks for your help and sorry for the long post
Good afternoon
