the bright side of that perhaps is that it really is turn off and not at all in sleep mode etc etc ?

i own Dell Axim X50v & X51v and i suspect the reason its hold switchworks because when u off windows mobile, it is still chewing the power while hibernate ? i could be wrong but i m just not going to bother to open them now to check the hardware design

Just got my replacement HM-801 today. I missed listening to it even though I only had the previous one for about a day.

This one has the Version 0.06 2009-09-25 Firmware and it has some major issues. It keeps defaulting to the same folder with each power up and when pressing the "back" button. (upper left front button). Also it takes up to 25 seconds to power up fully, because it always gets stuck with "Updating the hifiman HM-801 Media".

Also, confirmed. The Player still locks up when yanking the USB connection or Coax (using it as a DAC) when the power is still on. Only removing the battery or hitting the reset switch with a paperclip works.

You have to power off the HM-801 before disconnecting a USB or Coax DAC connection.

I would recommend sticking with the last Version 0.05 Firmware and be careful not to turn off "Now Playing" in the settings.

Another feature that is needed is when skipping tracks backwards (<<), a single press should skip to the beginning of the song you are listening to currently, not to the beginning of the previous track like it currently does. A double press within a 1/2 to 3/4 second should skip to the beginning of a previous track. This method of track navigation skipping is how it's been done on practically every CD player and DAP for a long time.

Also when navigating folders while browsing "SD Card" needs to start with the current folder that you are playing a song in (so you can navigate to a different song in the same folder, then allow single steps backward from the folder you are in. With Ver 0.05 pressing the "Back button (upper Lt front face button)" would go all the way back to the root of the SD Card. Ver 0.06 keeps defaulting to the same folder and then skips back one folder back.

Basically it should be the way that Rock Box is set up. It's pretty intuitive and works well.

Yes, just plug it in and it automatically switches to USB data mode. Two removeable drives show up. One is the internal flash I'm guessing, and the other is the SDHC card inside the HM-801.

Unlike disconnecting from DAC mode, unplugging the USB data does switch back to Player mode without always locking up. Takes awhile though.

Oh, yeah. Be sure to unplug audio connections like line out or headphone jack, because it often makes a weird, loud static noise when disconnecting the USB data connection.

Another bug.

I've heard other mentioning this one, but sometimes I hear a short static "Pttt" at the start of a song.

Also, I noticed the internal player does not recognize or play 24bit 88.2KHz files. HDtracks sells them, so be careful. Not all their high res content is 24/96.

Could you please provide the download link of these tracks? I have tested some 24bit 88.2khz files and the player does support them.
