Mpd starts playing dsf files as usual, but I get no sound.

Let me know if you need something else. Thanks!

Everything looks good. The specs only refer to DSD using DoP. Can you post the output of 'cat /proc/asound/DAC/stream0' ?

[ghost]

Sure thing.

I tried adjusting my audio output in mpd.conf to dop, but still no sound.

$ cat mpd.conf

audio_output {
        type            "alsa"
        name            "Aune T1se [DSD]"
        device          "hw:2,0"
        dop             "yes"
        dsd_usb         "yes"
        # Enable native DSD playback
        dsd_native      "no"
        # Select 32-bit DSD_U32_BE output format
        dsd_native_type "2"
        auto_resample   "no"
        auto_format     "no"
        auto_channels   "no"
}

stream0 output looks good. If DoP also does not work, that is really odd. Better check with Aune, maybe a firmware issue? Can you check DoP using another OS (Win/Mac)?

[ghost]

I tested it with foobar2000 on Win 8.1 and it just works. For some reason my mpd.conf works just fine with for example 24/192 flacs.

Also, while I was installing the drivers, I waded through the material that came with the T1se, and it would seem to be a dop device.

[lintweaker]

Is there a DoP or DSD indicator on the DAC? If so we could test DoP on Linux with a simple DoP file using aplay.

[ghost]

There are no indicator lights, but I got sound out of Deadbeef eventhough it’s choppy and cpu load rises to 50% (i7 @ 2.6GHz). With foobar2000 on Windows it was around 15% and without issues of choppiness or pops.

Does the recent mpd support dsd over pcm or should I stick with the dsd patched version while I’m trying to get this to work?

[lintweaker]

Both the official MPD and my patched version support DoP. MPD itself should not be the issue as DoP has been working for years now and no changes have been made to that part. There must something else amiss with your setup, no messages in the kernel log?

[ghost]

This is getting mighty strange. I went through dmesg and journal, and some debugging with mpd, but there were no clues. Oddly enough the ncmpcpp’s visualizer works perfectly – at least I can see what the dsd sounds like.

I think I’ll try some live mpd distros to see if they work and try to reverse implement their configuration files to my setup.

Since it’s no longer relevant to the native dsd, I’ll close this issue. Thanks for pointing out the DoP thing since it relieves me from investigating why that doesn’t work either ;).
