If you turn on the iDSD without connecting to the USB first it will use just the battery and will ignore and not use the 5v line from the USB for even when connected latter. You have to connect to an active powered USB cable with the iDSD turn off first and then connect the USB cable to the iDSD and just then turn on the iDSD then it will use the 5V from the USB cable and trickle charge the battery.

 

Try turning off the iDSD by turning the volume control down all the way counter clockwise and you will fell a click.  Disconnected the USB cable on the back of the iDSD wait almost 10 seconds and then reconnect the USB cable and the light should change to blue for charging while the iDSD is still turn off and let it charge overnight and the light should go out when the battery is fully charged. Then you can turn on the iDSD while the USB is still connected and the iDSD will be using the 5v power from the USB and trickle charge the battery full time. On my PC the USB 5v line is always active even when my PC is powered down. My PC always have the 5v standby power always active to the USB 5v line. Most of this is explained in the iDSD manual and my understanding from that. The red light means that the battery is weak.


I've tried charging it that way.  I'm using the USB cable supplied in the iDSD Nano box.  I assume that is the "active powered USB cable" you describe.  The unit is off, the blue charging light is initially on and then goes out.  So it's not clear whether the unit is still charging at that point or not.

 

When I check it later, I get the same behavior - blinking red light once the dial is turned on.

Hey guys, 

 

just got an idsd nano.

 

Why is it when my source files are 24bit, audirvana indicates that the dac is at 32bits?

 

for example, I'm listening to dave brubeck now with source at 24/176.4, but the output reads 32/96

I dont have that issue with JRiver - My 24/196 files are 'sent' 24/192 and JRiver has no knowledge or control over what the iDSD does from there. From what I have read, the iDSD upsamples ALL PCM to 32/384. I would say, that you should check your settings in audirvana.

I have tried various ways to charge the iDSD. My preferred way is with a high amperage 5v charger like you get from the wall for an iPhone etc. I just use my high amp battery charger that i bought for my iPhones etc. Again, turn off the iDSD, plug in the charger, you should see the blue light. Even with a high amp charger it should take many hours for it to charge from dead (red light). If the blue light goes out quickly even with the wall charger, I would say something is wrong with the iDSD.

I agree at this point. Since the red light start flashing as soon you turn on the iDSD this may be a issue other than the battery. If i understand you correctly this happens right after you flashed the firmware. You can try the latest firmware or open a support ticket at IFI web site at this point.

I've opened a support ticket with iFI.  So we're exploring the issues. 

 

I was able to get the iDSD Nano to change light colors (modes) as music was sent to the unit.  But there's still no sound coming from the unit.  So I'm guessing things are moving in the right direction.

I think I'd plug it into one of the wall type USB chargers overnight and then I'd re load the firmware two times...  it says this on their website.

Then I'd plug it into the computer and play around with it...

 

If your using windows then after you plug the idsd into the computer right click on the small speaker icon (lower right of the main screen) and open the "Playback devices"  and you should see the idsd... it probably wont be called idsd so one way to tell which one it is to watch the

playback devices window... and unplug the idsd and see what device went away... then plug the idsd in again and again watch the device window and when a new device is added chose that device with a right mouse click and goto properties..  and there you can name that device

idsd and change the icon to what you want it to be...  instead of a speaker icon...  :-)

Then highlight the new device you created and click " set default "      now you will see a green checkbox on your new idsd icon and your idsd should start to put out music...   if you want while in the device properties area you can click on the various items and there are "test" buttons that will let you test the connection that way...  now you will need to set up your playback program...

Happy iDSD Nano user. I can confirm the iDSD Nano works fine with an unrooted Google Nexus 7 2013 on stock Android 4.4, USB OTG cable and USB Audio Player Pro software.

LED color on iDSD corresponds with actual output as well.

Brand new to the Head-Fi forum....so...please be gentle.

 

I'm pretty much a newbie to all of this stuff, and I have a few "silly" questions.

 

The firmware issues....is this a Windows/PC only issue?  If I am connecting the Nano to a Macbook Pro, do I need to worry?

 

I also am attempting to connect the Nano to a Squeezebox Touch streamer.  I did so successfully earlier today, but I had signal dropouts and what seemed to be "buffering" issues between the Touch and the DAC.  Only with 24/192 files as far as I can tell. (I don't have any DSD files)

 

I didn't have this problem going out of the Mac.  I think the Touch is based on a linux platform.  Should I be updating firmware?

 

If the answer is yes, I'll probably ask HOW after that.

 

Thanks to all.

The firmware update to V4.02 solves some of the USB3 issues on MAC's as well.

The firmware downloadpage is a bit hidden on the ifi website: http://ifi-audio.com/ifi-xmos-firmware/, you can find instructions there as well, straight forward action.

Good luck,

Daan

But it looks like I will have to update it with a windows PC?? Is that right?

Yes. Or via parallels or other virtualization software running windows on the Mac.

Audirvana uses the maximum bit depth of the DAC or bridge by default. The signal is not affected by using the maximum bit depth, the unused portion of the depth is just padded with zeros. I am sure there is a better technical reference, but have found this for a little more on the topic:

http://www.computeraudiophile.com/f11-software/audirvana-1-4-a-14190-print/index34.html

You can also experiment with the sound difference between 24 bit and 32 as a check by using the Audirvana Preferences -> Audio System -> button at the bottom.

I would probably take the opportunity to ditch the Touch. I know its hard. I have the Transporter, and have moved on for some time now. Squeezebox Server has been abandoned, and at this point there are much better interfaces out there for PC or MAC. The PC/MAC is a much better basis for the USB DAC's of today (high res. DSD, etc.). I dont know about the Touch over USB, but I know that my PC over USB sounds much better than my Transported did over SPDIF.

it.. is. AWESOMEEEEEEEEEE.

 

 

listening to Chie Ayado's rendition of Mas Que Nada and the percussion is oh so sweet.

 

Way way way way WAY better than the FiiO E07K i used to have.

 

 

Using audirvana on a macbook air with Philips Fidelio X1 by the way.
