2010-08-06ALSA: hda - Make converter setups stickyTakashi Iwai
So far, we reset the converter setups like the stream-tag, the channel-id and format-id in prepare callbacks, and clear them in cleanup callbacks. This often causes a silence of the digital receiver for a couple of seconds. This patch tries to delay the converter setup changes as much as possible. The converter setups are cached and aren't reset as long as the same values are used. At suspend/resume, they are cleared to be recovered properly, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>

The commit afbd9b8448f4b7d15673c6858012f384f18d28b8 ALSA: hda - Limit the amp value to write introduced a regression for codec setups with amp offsets like IDT/STAC codecs. The limit value should be a raw value without offset calculation. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2010-07-09ALSA: hda - Limit the amp value to writeTakashi Iwai
Check the amp max value at put callbacks and set the upper limit so that the driver won't write any invalid value over the defined range. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2010-07-09ALSA: hda - Restore cleared pin controls on resumeTakashi Iwai
Many codecs now clear the pin controls at suspend via snd_hda_shutup_pins() for reducing the click noise at power-off. But this leaves some pins uninitialized, and they'll be never recovered after resume. This patch adds the proper recovery of cleared pin controls on resume. Also it adds a check of bus->shutdown so that pins won't be cleared at module unloading.

2010-03-30ALSA: hda - introduce snd_hda_codec_update_cache()Takashi Iwai
Add a new helper, snd_hda_codec_update_cache(), for reducing the unneeded verbs. This function checks the cached value and skips if it's identical with the given one. Otherwise it works like snd_hda_codec_write_cache(). The alc269 code uses this function as an example. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2010-02-24ALSA: hda - remove unnecessary msleep on power state transitionsZhang, Rui
This will save ~15ms boot time. The first 10ms sleep was introduced in commit d2595d86e5 for (buggy) Cxt codecs, so better to limit the sleep to the problem hardware. For the second 10ms sleep, the HDA spec says: Power State[1:0]: 00: Node Power state (D0) is fully on. 01: Node Power state (D1) allows for (does not require) the lowest possible power consuming state from which it can return to the "fully on" state (D0) within 10 ms, excepting analog pass through circuits (e.g., CD analog playback) which must remain fully on. 10: Node Power state (D2) allows for (does not require) the lowest possible power consuming state from which it can return to the "fully on" state (D0) within 10 ms. For modems, this is the "wake on ring" power state. 11: Node Power state (D3) allows for (does not require) lowest possible power consuming state under software control. Note that any low power state set by software must retain sufficient operational capability to properly respond to subsequent software Power State command. So 10ms is actually the max wait time. It should be safe to remove/reduce it and rely on the loop of 1ms-sleeps.

2009-12-25ALSA: hda - Disable tigger at pin-sensing on AD codecsTakashi Iwai
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.

2009-11-16ALSA: hda_intel: Digital PC Beep - change behaviour for input layerJaroslav Kysela
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>

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.
