And, does a similar problem like Grzegorz's case occur on your laptop? Some HP laptops (so far, AMD SB450-based) occasionally cause a hang-up during recording from the mic when HD is accessed. This is far more nasty problem, and it's interesting to know whether this happens on other chipset.
Hi Takashi. I've experimented a little with power saving in HD Intel Audio. I've noticed that using power saving with timeout set to 10 sec. solves my problem partially. When arecord stops recording I can turn it off, wait 10 seconds, and recording works back again. This is obvious, because power saving simply powers off and on device. I was wondering that maybe we can implement ioctl or something that will dump "state" (informations that will help in debuging) of device, when recording is not working, and "state" just after power on to compare what causes breakage ? Can you give me some tips about what informations are userful in debuging ?
