I (foolishly?) continue to try to get sound working on this laptop VL 5.8 Standard partition. I found something on the Web about a patch for the snd-hda-intel ALSA driver with SigmaTel CODEC. That's what I have, along with a STAC9200 whatever-it-is. A couple of people with Gateway laptops (what I have) reported success at last with the patch.
So I downloaded, compiled, and installed alsa-driver, alsa-lib, alsa-plugins, and alsa-utils for 1.0.15rc1, along with the patch for 1.0.15rc1, applied carefully following the directions. Everything looked good, but when I try to modprobe the new snd-hda-intel it won't insert and I get this (as copied from syslog):
Gateway kernel: snd_hda_intel: Unknown symbol snd_ctl_boolean_mono_info
So what do I do now? I Googled on the error and found nothing helpful. I can't see if the driver-plus-patch works until I get the module loaded, and the module won't load because of Unknown symbol snd_ctl_boolean_mono_info (the meaning of which I have no clue about).
I did run alsaconf, which identified the card correctly and which tells me I'm all set to go, but without snd-hda-intel I'm not going anywhere! Also, alsamixer won't come up because there's no snd_ctl_pcm or similar message. It's hard for me to gather all the information I need to report here because I haven't been able to get my wireless network working, so I copy things into text files I share with my Windows partition. I'm using VL in my VirtualBox virtual machine to write this, but the virtualized hardware there is completely different and has none of these issues.
Please tell me what to do about Unknown symbol snd_ctl_boolean_mono_info.
