After some hacking, I found that for some reason, something is calling
azx_send_cmd with nids much wider than 7 bits. This happens exactly
twice, once with nid=0x534c, and nid=0x8845. Both times, the verb is
0xf1c, and para=0x00. This clobbers parts of "val" in both
azx_single_send_cmd and azx_corb_send_cmd. I added the following code
to azx_send_cmd, and it works now:
if (!direct && (nid >> 7)) {
snd_printd(SFX "Uh oh, too wide an NID value. codec=0x%x,
direct=0x%x, nid=0x%x, verb=0x%x, para=0x%x\n", (codec->addr)&0xf,
direct, nid, verb, para);
return -EIO;
}
This outputs:
[136890.000388] ALSA
/home/mmullins/Desktop/alsa/alsa-driver/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:644:

I do realize that the problem is not completely fixed, and we still
need to figure out what actually calls azx_send_cmd with the offending
parameters. However, I am now lost in a sea of function pointers...
And it still doesn't work after a suspend, and I get a handful more
"uh oh"s upon resume:
