The Line Out volume will stay at the last volume setting unless you turn on LO Control in the settings. With LO Control on you can adjust the volume when plugged into the Line Out. Use the Line Out when connecting the AP10O to an amplifier as the signal from the Line Out is adjusted for that...

After some unsuccessful attempt to sell my AP100, I decided to use it as my daily PC's USB DAC. Pretty good I must say. Finally I can use it with music streaming services (Deezer, most of the time) thus far more variety than just my mSD Card  And now combined with Schiit Magni 2U, I think I've...

          Well, I went to check the website after seeing your post (oh my, they redesigned it, much better than the old one) and enter my ap100 SN to check.   Aaaaand it was not recognized too  Invalid serial number or something like that.   Which version of ap100 you own, the 1st...

I'm just curious, did anyone tried the line out of the AP100?   Correct me If I'm wrong, but isn't the volume in line out supposed to be fix/unchangeable?   Just this morning I plugged my headphone to LO, and yes, I can't change the volume (previously it sets on 35).   But then I put my...

I don't have any particular formatter software, since I use the default one from Windows 8.   But I suggest you to try other card first, because I had reformat the problematic card to fat32 and the problem is still there.

Are you using sd card? If so, try using another card, or just try it without any card.   I had the same problem with you in my first week of using AP100 (still in fw 067 i think, see my older post).   I switched the card (fat32 format) with another card (fat32 format too, smaller capacity)...

It's been a month so I think it's safe to say that my AP100 is stable now    It is a relieve after some initial crash and reboot problems with previous fw and sdcard     At first I thought my AP100 is a defect unit which crash and reboot with sd card inserted, but it looks like it is not the...

Yes, I did, as instructed in the manual.   And no, I haven't try other cards, so there still hope for my ap100 haha   ======================================================= Change of topic, i found this player to be a good match with RHA MA750i (bought this along the player as a bundle...

Sandisk ultra micro sd 32 gb and 69 firmware

  Did you have some other issues beside the scanning?   It was restarting randomly like crazy last time I put my sd card into it.   But since then (about two weeks ago maybe) I don't use any sd card and my ap100 working very well without problem.

Tried that but didn't work  For now the problem is solved by the way    Just need to observe the player stability for the next few days    Actually now there are more good news because finally my AP100 working normally even with the sd card  I don't know what happened but at least now I...

Well, somehow the reset button seems to work, AFTER I remove the sd card    So, this leads me to (temporary) conclusion that the sd card is the culprit    Let's see if another sd card bring same result or not    It's been working properly since last night using only the internal memory, no...

Alright, thanks for your suggestions    So there's good chance that my unit is at fault    Btw I am still using fw 067  Not brave enough to try unofficially released fw  But I think I will give it a try as the last resort    About shutting down, errr, I am unable to shut it down completely...

Well this is my first post in Head-Fi, so pardon me for some mistakes if there's any    So, I just bought this beauty about 4 days ago, and I really liked the sound right from the start and very satisfied. At least for the first day of use or so.   Then suddenly things became weird. The...
