Gapless playback is working excellent and this issue is also solved:

I put my system under heavy load, pressed 'x' like a madman and it worked perfectly!

Thanks @hwahrmann[DOUBLEPOST=1380213895][/DOUBLEPOST]Is it also possible to release a patch when MP 1.50 Final comes out? So we can enjoy your fixes

No fix, but i will create an Area 51 entry based on 1.5 Final

Unfortunately i have noticed another strange issue with this version: Channelpapping seems to be wrong. Steps to reproduce: 1. Start MP/MyMusic 2. Start playback of a multichannel HiRes .flac file (in this case FL, C, FR, RL, RR (RL & RR are empty). -> 3. Channels FL, C, FR, RL and LFE are mapped by MP.

i had a look at the logs that you've sent me and there are some things, which i don't understand.
Let me explain what happens.

1. I do a check, which modes are directly supported by the device:

You see there are only even channels listed.

the file that you are playing has 5 channels.

i do a check against the BASS WASAPI engine if a 88khz file with 5 channels is upported in WASAPI exclusive mode. And this check returns that it doesn't work.

And for some reason it falls back to 4 channels. i don't understand this at the moment.
Unfortunatley i have only Stereo on my Dev notebook, where i could do some debugging.

I'll see if i can do the checks in a different way.
I was introducing them, because during the tests for 1.4, when i implemented WASAPI, i've got some reports, that files couldn't be played.

I'll check with the BASS developers

@Helios61 The first post contains a new build.
When i find an uneven number of chanels, i will allocate 1 additional channel, which should produce silence.
Could you please try your multi-channel flac and post the logs?

 

[Helios61]

Hi @hwahrmann

With latest build playback of the multi-channel .flac doesn't work! Logs are attached!

 

[sikkek]

Finally got the chance to test again: gapless is working perfectly! Thanks hwahrmann!

On the issue of music not skipping: I found out that using F5 and F6 will skip as it should, however using a remote control (ff and rev) or arrow keys will not skip music. Any ideas on this issue?

 

[hwahrmann]

I found out that using F5 and F6 will skip as it should, however using a remote control (ff and rev) or arrow keys will not skip music

Yes. It seems that some other Plugin is stealing the REW and FF actions

 

[hwahrmann]

With latest build playback of the multi-channel .flac doesn't work! Logs are attached!

New build in first post.
Please test with your multichannel file.

this should also fix the delay in skipping

 

[Helios61]

Hi!
Playback unfortunately doesn't work. Logs are attached! It seems, that multichannel files with samplingrate >48,0 KHz doesn't work. 2ch/96,0KHz is working fine, 5.1ch/48,0 KHz too!

 

[hwahrmann]

But what worries me is that on the list of supported combinations it shows me 88khz and 6 channels.
And this is what i exactly try to do.
The call to WASAPI INit gives me an Unknown error. So no idea, what can be wrong.
I will write a test program.

Could you upload your test file and PM me the link?
