It's hard to say what scenario, but if we start to fix application bugs in driver level, than surely it will not going to be an easy task. > Is it worth trying implementing that (i.e. would such patch be > even considered)? As of it now, I'm not planning to add workaround to this, since I can not really test if it is working correctly. Also I just came back from holiday, and my mailbox is quite full, so do not expect that I can even take a look at this in the near future. Having said that.. since I do care about the twl4030 codec driver (and it's users), I will try to allocate time to fix it for you. > On Tue, Jul 6, 2010 at 12:40 AM, Liam Girdwood <lrg@xxxxxxxxxxxxxxx> wrote: > > Please port your app to ALSA, it's really the easiest option (look at > > aplay.c for programming sequence). > > The problem is not new apps, but legacy ones.

There might be kernel level fix for this, but it will take time. -- Péter _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
