There is no proper widgets (in HD-audio term, corresponding to registers) to behave for these purposes. On 2.6.25, you have additional "Master" volume and switch so that these won't matter much, I hope. > Takashi, if you need any other information which would help resolving > this, please let me know. First, make sure that you unmuted the hardware volume / mute via laptop keyboards. If everything looks OK ("PCM" adjusted, "Headphone" and "Speaker" unmuted) but still it doesn't work, it can be a driver problem. If you set CONFIG_SND_HDA_POWER_SAVE, try to undefine it. Or, try Ingo's patch Ted suggested. (To be noted, this couldn't get in to the mainline because this causes problems on other devices. 2.6.24-git already inclues this patch but with some workarounds.)
