Russ, he did not mean your DAC. His response was to one of mine, I have linked to a DAC. See above. Its a tiny little DAC, costs around 30 bucks and had been developed exclusively for the Raspberry. I was asking whether somebody had the chance to compare it to your proposed solution. They are different categories, though.

Bye, Andreas

I see, thanks for clearing that up. Yes that's definitely a nice piece of work for the money. I fully agree.

I have exciting news there too!

Look for another thread coming soon. I actually have something far better than AC2 already working. Brian and I are just finalizing the design.

Here is a teaser...

Cool !!! Great application would be a audio video player. If a video with multichannel audio is played, will the buffalo 8ch do the rest ? I don'e see any HDMI to I2S adapter coming.

Best Regards,
Davide

Thanks,

Davide

Yes, I found the best results streaming via network (both wired and wireless) from NAS. I also had excellent results using the RAM disk, but you can't fit much music on there.

I found using USB storage did not work well, even with an SSD.

Currently I am using a little RealTek USB wifi dongle (Edimax EW-7811Un - up to N150) that costs around $10 - and that works perfectly.

To make it work it's best turn off power management:

create this new file:

Code:
     sudo nano /etc/modprobe.d/8192cu.conf
then add this:
Code:
    # Disable power management

    options 8192cu rtw_power_mgnt=0
reboot, and your wifi won't fall asleep on you.

Hi Russ,

I've finished Buffalo III (it's fantastic, I've already wrote in TPA forum)
Also wanted to integrate some kind of embedded platform with I2S output to feed BIII

Raspbery Pi model B and Beagle Bone black were subjects of interest.
(BBB is out of stock everywhere, i'm waiting for next batch to buy it, with additional problem to get in my country, but will find somebody who travel...)
I have some questions and what i have already found, just to summarize:

1. I think BeagleBone BLack is better as audiphile server(don't want to go into war between two platforms, i like both), just BBB have newer chip which will have longer support in linux world, and here is not yet everything polished.

2. BBB will theoretically consume less power, because of newer chip

3. It have better Ethernet, not interrupted with USB serial com

4. it has two realtime integer processor inside AM3359 running at 200MHZ , we can program it for volume control, or BIII I2C control, with no affect on music reproduction

5. Both platforms are supported as far as I know, Volumio works on both, and I2s should work

6. Develeopers at Beaglebone are trying to push as much as possbile into linux kernel for it HW, also AM3359 is much easier for support than Broadcom in Rpi

7. About DSD, there are problems at the momment, I've looked into MPD and ALSA source code, there are definitions for bitstream DSD in ALSA, but MPD is not using it, nor any music client AFAIK. MPD have DSD over PCM, which BIII doesnot support, so we should make some changes into MPD, it is not too much of work, i will do that, when i get BBB (it will work on RPI also) and try to contact ALSA dev for full integration.

If I understood you correctly, you alse have Beaglebone Black, did you try the same thing on it (Volumio) ?

Regards

I bet that if Russ created a simple and effective method for people connecting the pi/BBB to the b3se, most won't need USB for audio anymore. Just add a pi to your current bufalo dac and put the streamer/USB receiver on sale!

I am definitely still open to using the BBB.

I did use it with volumio for a while, but they were not supporting I2S out at the time. I will check again.

What's great is that even though the rpi may seem humble, it actually makes a really good streaming appliance! I am actually quite impressed. It easily beats a Squeezebox etc...

I will let you know what I find with the BBB
