The error messages (at least some of them) are known issues and I already posted the problem on alsa-devel ML. The fix should be easy but I'd like to get consensus beforehand. Other than that, I'm really not sure what you want in the previous posts; it were merely a dump from some command invocation, and that's all what you wrote. If you want us to fix something, *please* write / report more explicitly. Only pasting an error message isn't better than some bot. > alsaucm -c xxxx set _verb HiFi set _enadev Speaker > https://www.systutorials.com/docs/linux/man/1-alsaucm/ > > I used alsa-utils 1.17 and alsa-lib 1.17. Thanks, that's at least some more background for better understanding. Currently alsaucm is so-to-say broken. Just avoid using it until it gets fixed. PA shouldn't hit the problem, it seems almost only alsaucm. thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
