I checked my old notes that the version of the firmware I have installed is

1.02 RevC3. Seems to work fine with the latest 1.056 driver. I'll wait a few days until people are happy before updating the firmware. :-)

On a separate note, how many people have tried playing 352/384K?

I cannot get a signal lock on this sample rate (complete silence) and I thought it could be the reclocking circuit I installed. However, there are other reports of not being able to play 352/384K with Buffalo III DAC.

Can you share your setup?

Thanks in advance...

Did latest firmware, everything now working perfectly, and sounding pretty damn good .
PCM to 352/384Khz both native and upsampled, DSD files play both channels, no switching problems- perfect!
I'm using Amanero/Buff2/Jriver.
Thanks for updates, support.

I have tested the latest firmware/software with my Buffalo24 set-up and the reset works perfectly. Also no need to map channels for playing DSD. 352khz PCM plays well too. The only issue I have found is that there seems to be an absolute inversion of channels for all modes so what is left comes out of the right earpiece and vice versa. This needs to verified by other people to make sure that it is not just my set-up issue.

In the 1.55 firmware there was a fix to accept a reset command from the driver but this command was ignored during DSD/PCM switch.

Now i uploaded a firmware 1.56 that fixes the reset command sent by the windows driver during DSD/PCM switch.

Let me know if it's all ok.

Thanks,
Domenico

I've done some 352.8 and 384 testing with a stock B-III (100MHz XO) using Foobar in both KS and WASAPI output modes. For DXD a 2L sample file was used, for 384KHz a 96KHz file upsampled 4x with SOX (0.81 mod1 plugin). In both cases there was heavy stuttering present no matter what buffer size was used. CPU usage was <30%. Lastest Amanero drivers and firmware.

I've managed to play both 352 and 384 through my (100MHz) Buffalo 2 without any issues or stuttering. Very occasional dropout during first couple of minutes after switching the Buffalo on, but no where near as bad as some others have reported. I updated to the latest firmware this morning and I am using driver 1.0.56. CPU on a Atom based PC is around 10% playing 352 via KS - WASAPI uses about 35%. DSD works using the method glt has detailed in his blog, with similar CPU usage.

Must say I'm very happy with the way this is working now - especially considering I haven't put any attention into the I2S cabling, just a temporary fix up of about 100mm length.

With 384K, BCK is 24M, so you cannot reclock with same speed XO, just use the XO for the BCK works fine.

Thanks

Default DSD128

Still no luck with DSD128 under foobar with ASIO4ALL showing @44100 HZ. With DSD64 it worked correct showing @176400 HZ. It seems driver is missing 24/352K or 24/384K mode. With ASIO and WDM support, do we need to have 352K/384K sample rate supported under sound card setting, I only have up to 192K supported.

Hmmm starting to get dropouts when upsampling 44.1 to 384, seems ok at 176.
Have a bad noise problem with laptop power supply. Plugged in there's a lot of RF/HF noise through the system, even with no music playing. Unplug the PS and noise goes away, doesn't happen with Exa I2S device with same laptop.
With PCM the exa/buff is smoother, more natural sounding than the amanero/ buff, but the amanero/buff is just sensational with DSD.
