Re: 3.19 on Nokia n900: audio quality awful

Hi!

If you have any idea about playback problems, help would be still
welcome. I'll have to do bisect, otherwise, and it will not be easy.

I tried audio recording this time.

In 2.6.28-nokia, it is neccessary to set "Input select" na "digital
mic", then it works. Input select being in "playback" option makes it
easy to miss.

In 3.18 and 3.19-rc3, all I can record are zeros.

Does playback/recording work for you on OMAP 3430-based machines?

Thanks,
