[gentoo-user] Which sound codecs do I need?

[gentoo-user] Which sound codecs do I need?

[Walter Dnes]

  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.

Well, since you're too busy to use Google, let me do that for you ;-)

The sound chip is a Realtek ALC888.  I'm sure this is all the info 
needed to select the correct driver.

Or lspci -k would tell what driver the CD was using, if sound worked 
which I bet it did.

  Your Google-fu is stronger than mine.  I did try Google, but it didn't
occur to me to use that specific search.  Anyhow, thanks for the info.

  That tells me which *DRIVER* is in use (so does "lspci -v" for that
matter).  It does *NOT* tell me the *AUDIO CODEC*.  "lspci -k" shows...

Yeah, the intel_hda system is pretty funky. My understanding is that
the API is essentially a programmable plugboard connecting the various
DSPs on the chip, and that the "codec" is a mapping of which pins
connect to which.

Kinda neat, actually. You'd think someone clever would try expressing
that interface more intuitively to the user.
