Known PCM bug in ymfpci on Tecra 8100

Known PCM bug in ymfpci on Tecra 8100

[Bryan Bennetts]

Hi,

Has anyone had any joy fixing this problem?  If not is there anything I can do 
to help?  I am willing to attempt debugging if someone will point me at a 
'dummy's guide' to attaching a debugger to ALSA. 

Sorry if this was a dumb question, I can see the bug is known but couldn't 
find any open bug in the bug tracker.

Cheers, Bry.

Hmm, in the ymfpci description it has :

  Known bugs

  - pcm playback is not audible on toshiba tecra8100. 

I _do_ get sound, unfortunately its just crackly static noise:-(

I shall raise it as a bug.

Cheers, Bryan.

Ah, that one...

Yes, please.
It's likely the lack of some register initiailzation, since OSS ymfpci
and the old ALSA 0.5.x ymfpci seem working.  The question is which
register affects this.

Raised : 384

I'm happy to have a bash at debugging it, although I have never done any driver dev so there may be an amount of hand holding required.  Alternatively I can provide whatever outputs you want.

Cheers, Bry.
