I've been having a few problems with sound lately:

1. The PCM channel is available in alsamixer, but not kmix. This went away
with the latest round of KDE updates.

2. The master channel does not turn off the sound when set to zero. It
gets lower, but not low enough. The PCM channel has to be turned down for
the sound to actually get quieter. KDE 3 didn't have this problem.

3. What is this error: Unknown hardware: "HDA-Intel" "Nvidia MCP67 HDMI"
"HDA:10ec0888,18491e01,00100001 HDA:10de0067,00670000,00100000" "0x1849"
"0x0888"? I don't remember which kernel I was running when I first saw it,
but it's also relatively new.

I'd guess that the change in KDE was made intentionally to simplify the
mixer, so submitting a bug is not likely to help you. Use alsamixer.

To turn off the sound, use "mute". (If it exists.)

This isn't an error but a warning. There are no saved mixer settings,
and your specific model isn't known, so the mixer controls are
initialized with generic default values.

If you set the volumes with alsamixer and then run "alsactl store", this
message will vanish.

It means YOUR version of Alsa doesn't really support _this_ variety
of the HDA-Intel sound on the motherboard (HDA-Intel is a sort of
container name, the actual sound processor chip may vary).

Try installing a newer version of Alsa (especially the kernel modules
FOR your release of the kernel).
