I'm installing Gentoo on an older Intel Core2 Duo machine from Dell for some testing. Checking with "lspci -v" from the install CD shows...
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02) Subsystem: Dell Inspiron 530 Flags: bus master, fast devsel, latency 0, IRQ 43 Memory at fdff4000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel Capabilities: [130] Root Complex Link Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel In "make menuconfig" I get a whole slew of codecs, i.e... CONFIG_SND_HDA_CODEC_REALTEK CONFIG_SND_HDA_CODEC_ANALOG CONFIG_SND_HDA_CODEC_SIGMATEL CONFIG_SND_HDA_CODEC_VIA CONFIG_SND_HDA_CODEC_HDMI CONFIG_SND_HDA_CODEC_CIRRUS CONFIG_SND_HDA_CODEC_CONEXANT CONFIG_SND_HDA_CODEC_CA0110 CONFIG_SND_HDA_CODEC_CMEDIA CONFIG_SND_HDA_CODEC_SI3054 The only one I'm confident eliminating is CONFIG_SND_HDA_CODEC_HDMI due to the help saying "Say Y here to include HDMI and DisplayPort HD-audio codec". This is an older machine, and doesn't have a card or chip with HDMI and/or DisplayPort. -- Walter Dnes <waltd...@waltdnes.org>
