Raspberry Pi/Runeaudio often can't find Ayre QB9 DSD

[charlesttchen]

Dear all, I've been using Runeaudio 0.2 with Ayre QB9/non-DSD for a few months and can't live without it! After upgraded to QB9/DSD, I haven't been able to set it up smoothly. First of all, Runeaudio 0.2 played music in bits and pieces. I can't get the music going for more than 5 seconds without pausing for a few minutes. As you know that's unbearable. I tried using Runeaudio 0.3 beta but it can't recognize Ayre QB9 DSD at all. At one point I saw Ayre USB DAC in the audio output section but next time it's gone. I tried switching 3 different USB cables and none of them has stable result.

It it possible that certain DACs requires more CPU power from the player?

Other than that, in my set up, UI is very often to hang with the "CONNECTING" message going forever. Turn the power off and on can't fix the issue and I've re-installed Runeaudio 3 times since last night.

Any thought? Thank you!!

Hi charlesttchen,
are you using a PSU of at least 2A of current? DACs are not CPU hungry but they could be current hungry.
Please post your debug info like described (refresh the debug info page a couple of times before copying the content).

Hi ACX, Thank you so much for the prompt reply. Yes I do use linear power supply with 2A current power. To be safe, I tried the power supply came with squeezebox touch (which is 5V/3A) and the results are still the same. Ayre/QB9 uses internal power supply so I don't think it's a issue there.

I focus on Runeaudio 0.2 as it's closer to working. Now I can play music to analog output, airplay to USB DAC, but can't play any internal/NAS music file to USB DAC. Runeaudio turned to "Pause" when I pressed "Play". Here is my debug info (sorry for the long post, I'm to sure if I did it right)

Thank you so much AndreR! I enabled the audio output and it can play USB stick via USB output. That's great.

However, when I connect a powered HDD to the rPi USB port and try updating the database , the yellow lights on rPi went dark and on a few times over the next 5 minutes, while both web GUI and Putty are not responding. The same situation happen when I try updating database on NAS.

Appreciate for your help!!

Best Regards,
Charles

Thank you again AndreR. I switched to another linear PSU with 3A capability, and now the NAS database update can be done. All other outputs are disabled except for the USB output. But I still can't play any file from my NAS. Runeaudio turned into pause+occasionally broken sound for 1 second, as my previous post. Does that mean QB9 DSD is particularly CPU/current hungry ? I can't really find any PSU that can do more than 3A...

Here's my debug file http://pastebin.com/YJ2zPhFb (Thank you ACX)

Best REgards,

Let me understand it better: was your DAC working with 0.2-beta?
Have you tried to switch between different kernel version in the Settings screen? If not give it a try. Reboot after applying the switch and see if something changes.

Thank you ACX!

QB9(non-DSD) + 0.2beta: Everything OK

QB9(DSD):
0.2beta: Can see USB DAC output. Airplay OK. USB stick play OK. NAS play: Runeaudio paused forever with occasion 1-second-music every few minutes.
0.3beta: Cannot see USB DAC at MPD/web GUI. Here is the debug file http://pastebin.com/eCXSG5L6
0.3 Alpha: Can see USB DAC output. Airplay OK. USB stick play OK. NAS play: Runeaudio paused forever. Debug file: http://pastebin.com/Xuh633TF
