#94 Playback of WavPack files with DSD audio inside fails

[ManniX-ITA]

Playback of WavPack files with DSD audio inside fails, works find with input_sacd.

[Maxim V.Anisiutkin]

Could you share such WavPack file, please?

[ManniX-ITA]

Sent you a PM

[Maxim V.Anisiutkin]

I tested this file with foobar v2.24.1 and foo_input_udsd v0.1.0 for x64/x86. Playback and tag editing worked normally. What doesn't work in your setup? If foobar crashed, please send me crashdumps as well.

[ManniX-ITA]

That's really weird, maybe it's having issues with another plugin?

Opening track for playback: "file.wv" / index: 1
Unable to open item for playback (Unsupported format or corrupted file):
"file.wv" / index: 1
Error: Cannot open MD5 hash source
Unrecoverable playback error: Unsupported channel layout

Will check with the portable version.

I should have tested more Wavpack files sorry, I don't have many :P

Not sure how it gets to this issue about the unsupported channels layout.
It's anyway interesting that input_sacd is more robust and can handle it, while input_udsd ends up with this error.

The root cause is the WavPack which is messed up.
I had in the same directory the DSD64 and works perfectly.

It doesn't work even with the portable version, only your plugins installed.
The behavior depends also on the audio output, I didn't think about it.
Somehow the frequency of the DSD256 is not read correctly from the WV.

I see when playing the same Wavpack but with DSD64 inside:

DSD64 | 5645 Kbps | 2822400 Hz | stereo

But with the DSD256 version:

WavPack | 11176 Kbps | 1411200 Hz | stereo

What is that? DSD32? :)

This is not a problem if I use DirectSound/WASAPI output but it is with ASIO, the error is more helpful:

Unrecoverable playback error: Sample rate of 1411200 Hz not supported by this device

So this wrong frequency is passed out and in my full installation this causes the "unsupported channels layout"

[ManniX-ITA]

Seems the problem is not in the file but in the foobar's WavPack decoder.

I used EZ CD Audio Converter to create another WP DSD version from the original.
The original is correctly read by EZCD, no issue.

The new version does exactly the same with foobar.
Only difference is in how the codec is shown in the playlist when not playing the file.
The original shows DSD256, same as the DSD64 version, but the codec both in the status bar and the playlist changes to WavPack once you start playing the track.
Instead of setting the correct frequency and bit depth as with DSD64, it's set to 8 bit and the frequency divided by 8.
Doesn't look like a great idea... it's probably mistakenly identifying the payload as PCM.

I will check if there's an issue open for this on the WavPack decoder.

[Maxim V.Anisiutkin]

Yes, you are right, some fixings in file info are definitely needed.

[Maxim V.Anisiutkin]

Please check v0.1.1. Reload info tags before playback.

[ManniX-ITA]

Thanks awesome!

Now on the portable install seems to work, I can see the right frequency reported.

I still have problems with my main install and I'm struggling to fix it.
It doesn't work with input_udsd, not input_sacd, and I get always the "Unrecoverable playback error: Unsupported channel layout".
It's driving me nuts, any idea?

[ManniX-ITA]

I had to go back to input_sacd on my main install, input_udsd doesn't work with WavPack and I can't find any reason why.
Can't risk to destroy it, too much deep customization.

BTW both are incompatible with the Fading in Output; once enabled input_sacd crashes in a couple of seconds, input_udsd randomly and foobar never closes when exited (zombie process).
Is that a known limitation?

[Maxim V.Anisiutkin]

If you zip and share your foobar setup (C:\Program Files\foobar2000, C:\Program Files (x86)\foobar2000, C:\Users\<user>\AppData\Roaming\foobar2000) I'll try to make it out.</user>

[ManniX-ITA]

I'll open a private ticket (never used before).
Thank you!
