* ALSA: hda - Disable tigger at pin-sensing on AD codecsTakashi Iwai2009-12-25
| | | | | | | | | | | | Analog Device codecs seem to have problems with the triggering of pin-sensing although their pincaps give the trigger requirements. Some reported that constant CPU load on HP laptops with AD codecs. For avoiding this regression, add a flag to codec struct to notify explicitly that the codec doesn't suppot the trigger at pin-sensing.

* ALSA: hda_intel: Digital PC Beep - change behaviour for input layerJaroslav Kysela2009-11-16
| | | | | | | | | | | | | | | | Original implementation was keeping registered input device for SND_BEEP and SND_TONE events all time. This patch changes this behaviour: If digital PC Beep is turned off using universal control switch, the input device is unregistered. Explanation: The kd_mksound() send SND_BEEP and SND_TONE only to last registered device acceping those events. It means that the HDA Intel audio driver blocks also the internal PC Speaker device (pcspkr.c driver) even if the HDA Beep is muted. The user can easy disable all beeps using 'setterm -blength 0' or 'xset b off' command. Signed-off-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - Add power on/off counterTakashi Iwai2009-11-11
| | | | | | | | | | Added the power on/off counter and expose via sysfs files. The sysfs files, power_on_acct and power_off_acct, are created under each codec hwdep sysfs directory (e.g. /sys/class/sound/hwC0D0). The files show the msec length of the codec power-on and power-off, respectively. Signed-off-by: Takashi Iwai <tiwai@suse.de>

So far, patch_sigmatel.c calls its shutup routine for avoiding noises at reboot on some HP machines.

| * ALSA: hda: track CIRB/CORB command/response states for each codecWu Fengguang2009-08-03
| | | | | | | | | | | | | | | | | | | | | | | | | | Recently we hit a bug in our dev board, whose HDMI codec#3 may emit redundant/spurious responses, which were then taken as responses to command for another onboard Realtek codec#2, and mess up both codecs. Extend the azx_rb.cmds and azx_rb.res to array and track each codec's commands/responses separately. This helps keep good codec safe from broken ones.

* | | ALSA: hda - Reduce click noise at power-savingTakashi Iwai2009-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add some tricks to reduce the click noise at powering down to D3 in the power saving mode on STAC/IDT codecs. The key seems to be to reset PINs before the power-down, and some delay before entering D3. The needed delay is significantly long, but I don't know why. Signed-off-by: Takashi Iwai <tiwai@suse.de>
