Re: [HDAudio][ALC295] speakers not working on Acer Travelmate P614

Hello Takashi,

as I am new to mailing lists I would like to know how to proceed now, after I 
posted the question here. Because I cannot create quirks on my own and need 
someone to guide me. But it seems that no one is answering to the question 
anymore. 

Is it normal and will it be attended at some point? Or do I have to post it as 
a BUG somewhere (e. g. linux kernel)?

I do not want to hurry you or anyone else here in any way but I would like to 
know whether I have to wait or to do something.

I would be happy to test some more ideas (like COEFFS and stuff like that) but 
I need concrete recipes for it.

Thanks,

Stanislav
