Hi everybody, well I send this message because I've got a problem with Baytrail audio port (rt5640). I followed the discussion about writing an alsa driver (see it : http://mailman.alsa-project.org/pipermail/alsa-devel/2015-June/094114.html) and I tried many solutions (as like that : https://groups.google.com/forum/#!topic/android-x86/GKBFxCZyxQg ).
Now the system see the Baytrail card audio for speakers but as Michele Curti when I start the system I've got a minute freeze and I haven't got still sound. When I launch dmesg command, I see only those messages :
Baytrail Audio Port: sst: error code = -22 bytt100_rt5640 bytt100_rt5640: BUG: , pos = -22, buffer size = 3840, period size = 480 Do you know how I can solve this problem and it is possible to operate baytrail audio device with alsa or pulseaudio ?
it looks like you are using an old kernel, the t100 name was removed quite a while ago. also without details about your codec we can't help you.
