Been using the odac for about a month now and very impressed! I use it with Foobar and wasapi on a Win7 PC. With Foobar (preferences - output - output format) and the odac (control panel - sound - properties - advanced) both set to 24 bit (or any other combination for that matter), the Windows volume still works, I had expected this not to be the case as wasapi by passes the windows controller, has anyone else experience of this?

From his experience the Pi is not able to handle the ODAC with bit perfect output settings. 16bit CD quality seems to work fine with it. Best Regards, Stefan

I want to share my experience with odac. I bought odac to drive my power amp and floorstanding speakers. I have tested it with my notebook and brother's. Everything was working OK and sound was very good, compared to notebook integrated crap sound. I decided to connect odac to my girlfriend HP notebook. The sound was very distorted. I didn't understand why.... I have done a lot of google search to find out, why it sounds so bad. The problem was here:
What Is the AMD USB Filter Driver? | Tech Tips - Salon.com Maybe this information willl help for others, who has notebooks with amd chipsets and has distorted sound with odac. Usually amd usb filter is installed when you buy new notebook with factory installed OS and drivers, and you won't have problems with odac, but I always do clean install to get rid rubbish software which installed by manufacturer. So don' forget to install amd usb filter if you also do clean instal. |

The notebook issue can be caused by its switched power supply. I tried USB DAC with ASUS low-end notebook and then connected to desktop speakers. The interference was so high that it was not pleasant to listen to anything. I've tried to replaced power supply with the one from old Thinkpad and the distortion has disappeared.

I replaced fb102 and it didn't fix anything. I also noticed that ESD1 and ESD2 are missing from my board. The replacement I just got has something in both of them. Any ideas what they are? could I just short them and see if I get anything?

I just received my ODAC in the mail and I've been testing it against an internal Terratec Aureon 7.1-Space sound card in my PC, connected to a NAD C 352 amplifier with a pair of B&W DM603S2 speakers. I can't hear a difference. Not that I necessarily expected to; one of the reasons I bought the ODAC is to avoid the loud sound output by the analog out of my sound card when my computer is turned off. Also, it makes me able to have devices without a sound card output sound to my stereo.
One thing that disappointed me though was the noise floor. It's exactly the same as that of my internal sound card. When nothing is playing on the ODAC, it's silent. Probably because it's not outputting anything. But when I play a WAV file with silence in it, its noise floor goes up to exactly that of the internal sound card. The noise floor of the internal sound card is the same whether I play anything on it or not though. Interestingly, when I connect the ODAC to my Raspberry Pi, the noise floor disappears almost completely. So as far as I can deduce, noise is being transferred from my PC over the USB cable to the ODAC. |
