Sound card error messages in dmesg

[smolloy]

Hi guys,
I've found the following repeated over and over again in dmesg,

ALSA sound/core/control.c:635: BUG? (info->access == 0)

Call Trace: <ffffffff881e000f>{:snd:snd_ctl_elem_info+147}
       <ffffffff881e0d04>{:snd:snd_ctl_ioctl+630} <ffffffff8018b6c9>{do_ioctl+33}
       <ffffffff8018b95b>{vfs_ioctl+584} <ffffffff8018b9d6>{sys_ioctl+98}
       <ffffffff8010a7b6>{system_call+126}

Does anyone know what it means? My sound card appears to work fine, since I can play CDs, and chat on Skype, but I'd really like to know what this error means, and what I can do about it.

I've searched on the term "sound/core/control.c:635: BUG?", but there are only a couple of not-very-useful hits.

Can anyone help me with this?

Any idea what this means? What should I be searching for?

I hate the feeling that there's something 'wrong' with my computer -- even if it appears to be running smoothly -- and the continual recurrence of this message is starting to get to me!

Can anyone help me?

I guess no one knows the answer to this.

My audio hasn't been running as smoothly as it should. ~50% of the time skype refuses to work, and sometimes there's no sound from online videos. A reboot normally fixes things, but this isn't an acceptable solution. When this message appears in the logs it repeats dozens of times inside a few seconds.

Does anyone have any ideas?
