It worked for me. thanks, this worked for me also (at least to resolve the permissions issu= e) now, I lost a bit the discussion thread, because it was some time ago I last wrote, and I'm also having a lot of work for university. let me summary things up now: - - hardware is Ericsscon HBH-35 and a SiW based usb dongle - - software is gentoo-dev 2.6.10-r5, with mh4 patch (also tried a vanilla, with same results) - - the problem is, btsco connects and I can set the volume and hear hissing sound, but I can't hear anything using aplay or others (they just hang there), nor set the loopback option - - I tried my friend's dongle, with other chipset, and everything just works fine; anyway I'd of course rather to be able to use _my_ dongle :) Lars pointed out some times ago that there was an issue with handles. here I report what he told: | I asked Marcel on this list, but I did not understand his answer...: |> the Silicon Wave chips are not the best ones.
