if you have the similar problem that we had two years ago, it was not an alsa issue, but an issue of the cardbus bridge ... in that case, you should get in touch with the pcmcia-maintainers of the kernel ... the mailinglist is linux-pcmcia <linux-pcmcia@xxxxxxxxxxxxxxxxxxx> ... you could also ask Daniel Ritz <daniel.ritz_at_gmx.ch> directly, who was a great help solving my problem, which resulted in a kernel patch for my former o2micro cardbus bridge ... possibly it's helpful for them, if you can get a data sheet of you cardbus bridge and maybe even get in touch with the manufacturer, if that information isn't sufficient ... hth ... tim -- TimBlechmann@xxxxxx ICQ: 96771783 http://www.mokabar.tk You can play a shoestring if you're sincere John Coltrane
