I see someone that had sounds working on a Thinkpad T61, but sounds have recently stopped working. The module snd-hdsnd-hda-intel is listed on his lsmod output as below. I've never seen such a module before. Any info on what this module is?

lsmod | grep snd_hda_intel returns:

snd_hdsnd_hda_intel 324248 2 snd_pcm 62596 2 snd_pcm_oss,snd_hda_intel snd 45604 12 snd_pcm_oss,snd_mixer_oss,snd_hda_intel,snd_pcm,snd_seq_oss,snd_seq,snd_timer,snd_seq_device snd_page_alloc 7816 2 snd_hda_intel,snd_pcm a_intel 324248 2 snd_pcm 62596 2 snd_pcm_oss,snd_hda_intel snd 45604 12 snd_pcm_oss,snd_mixer_oss,snd_hda_intel,snd_pcm,snd_seq_oss,snd_seq,snd_timer,snd_seq_device snd_page_alloc 7816 2 snd_hda_intel,snd_pcm

This is on a Debian Lenny install, using kernel 2.6.26-1-686, and alsa driver version 1.0.16. Codec is AD1984.

His soundcard is detected ok, as below.

$ cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xfe020000 irq 17

This is only out of academic interest, but as modinfo shows no such module, I'm really puzzled how a non existing module can be loaded.
