[Voyage-linux] Re: voyage-mpd and Ayre QB9

[Demian Martin]

We have had good success with Voyage Linux, the latest Alsa (1.0.23 &
1.0.24) and The Wavelink from Wavelength that uses the same code for the USB
interface. Here is the specific section of MPD (again latest) that we use:

audio_output {
       type          "alsa"
       name          "USB"
       device        "hw:1"    # optional
       mixer_device  "hw:1"        # optional
       mixer_control "PCM"         # optional
       mixer_index   "0"           # optional
}

This bypasses any other setup configs in the system and you may need to
figure out the ID of the usb device, use aplay -l to identify it. This has
worked well with any of the USB devices we have tried, however there are
very few UAC2 devices in the world that do not use Gordon Rankin's code.
Those that do I have been unable to get for testing yet.

Hi Maarten, dear all,

The problem is not solved for me. The status is that I got via the German
distributor into contact with  Ayre. After I had sent them a lot of
debugging
output from various Linux computers they tried themselves to connect a
current QB-9 to an Ubuntu machine - and they confirmed to get the same
result as me. They told me that they want to look into this, but since one 
week I didn't get any further response. 

Please, also contact your dealer and distributor and maybe also the Ayre
support directly - in the hope that this increases their priority level for
this problem! 

I think this is not a voyage specific problem, I tried various older and
newer Linux versions on various machines, but always the same problem 
(the mode switch of the QB-9 in A position, i.e. class 1 up to 96/24,
this I think is expected to work with any of the Linux versions I tried;
the newest kernel/ALSA would only be needed for the class 2 support
up to 192/24).

The sound of the QB-9 is really great, I really want to get it working
with my Alix/Voyage system!

Best regards,
   Frank

PS: As a temporary workaround I managed to put a Win XP Prof SP2 on my
Alix, headless with tightvncserver. But this is very unstable and 
just reboots itself every few hours for no reasons I can see. Anyone 
with experience on this?
