Hi, I am the ALSA user that started this thread in the alsa-users list. I found that my strategy of adding the "index=0" option and praying was nos stable enough, and each time I updated alsa or my kernel I had to pray again to get the subwoofer working. I tried Tobin's patch and finally I got the LFE control again (which I had lost 4 hours ago by updating alsa and the kernel). If there is anything I can do to get this problem solved, just let me know and I'll be more than glad to help. Regards, - Celso Gorrín. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
