Seems as if the hardware dependant codec drivers aren't getting compiled
in. After adding to the Makefile:
EXTRA_CFLAGS := -DCONFIG_SND_HDA_GENERIC \
-DCONFIG_SND_HDA_CODEC_REALTEK \
-DCONFIG_SND_HDA_CODEC_CMEDIA \
-DCONFIG_SND_HDA_CODEC_ANALOG \
-DCONFIG_SND_HDA_CODEC_SIGMATEL \
-DCONFIG_SND_HDA_CODEC_SI3054 \
-DCONFIG_SND_HDA_CODEC_ATIHDMI \
-DCONFIG_SND_HDA_CODEC_CONEXANT \
-DCONFIG_SND_HDA_CODEC_VIA
My box works again. The chip for my HP nc6320 detects as a AD1981, thus
requires the CONFIG_SND_HDA_CODEC_ANALOG option.
In the kernel sources, the unused HDA driver has in hda_patch.h
static const struct hda_codec_preset *hda_preset_tables[] = {
snd_hda_preset_realtek,
snd_hda_preset_cmedia,
snd_hda_preset_analog,
snd_hda_preset_sigmatel,
snd_hda_preset_si3054,
snd_hda_preset_atihdmi,
snd_hda_preset_conexant,
snd_hda_preset_via,
NULL
};
in the l-u-m version in hda_patch.h:
static const struct hda_codec_preset *hda_preset_tables[] = {
#ifdef CONFIG_SND_HDA_CODEC_REALTEK
snd_hda_preset_realtek,
#endif
#ifdef CONFIG_SND_HDA_CODEC_CMEDIA
snd_hda_preset_cmedia,
#endif
#ifdef CONFIG_SND_HDA_CODEC_ANALOG
snd_hda_preset_analog,
#endif
#ifdef CONFIG_SND_HDA_CODEC_SIGMATEL
snd_hda_preset_sigmatel,
#endif
#ifdef CONFIG_SND_HDA_CODEC_SI3054
snd_hda_preset_si3054,
#endif
#ifdef CONFIG_SND_HDA_CODEC_ATIHDMI
snd_hda_preset_atihdmi,
#endif
#ifdef CONFIG_SND_HDA_CODEC_CONEXANT
snd_hda_preset_conexant,
#endif
#ifdef CONFIG_SND_HDA_CODEC_VIA
snd_hda_preset_via,
#endif
NULL
};
Presumably we want to build all of these. CONFIG_SND_HDA_GENERIC isn't
used in the linux kernel version either, just l-u-m.
