2014-02-28ALSA: hda - Fix registration of beep input deviceTakashi Iwai
The beep input device is registered via input_register_device(), but this is called in snd_hda_attach_beep_device() where the sound devices aren't registered yet. This leads to the binding to non-existing object, thus results in failure. And, even if the binding worked (against the PCI object), it's still racy; the input device appears before the sound objects. For fixing this, register the input device properly at dev_register ops of the codec object it's bound with. Also, call snd_hda_detach_beep_device() at dev_disconnection so that it's detached at the right timing. As a bonus, since it's called in the codec's ops, we can get rid of the further call from the other codec drivers. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-03-18ALSA: hda - Fix power-saving during playing beep soundTakashi Iwai
While playing the digital beep tone, the codec shouldn't be turned off. This patch adds proper snd_hda_power_up()/down() calls at each time when the beep is played or off. Also, this fixes automatically an unnecessary codec power-up at detaching the beep device when the beep isn't being played. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-07-03ALSA: hda - Get rid of superfluous beep->mode fieldTakashi Iwai
It's no longer necessary since beep_mode=2 option was dropped. It can be checked simply via codec->beep != NULL. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-07-03ALSA: hda - Remove beep_mode=2Takashi Iwai
The beep_mode=2 option was introduced to make the beep mixer controlling the beep input allocation/deallocation dynamically, so that a user can switch between HD-audio codec digital beep and the system beep only via mixer API. This was necessary because the keyboard driver took only the first input beep instance at that time. However, the recent keyboard driver already processes the multiple input instances, thus there is no point to keep this mode. Let's remove it.

2011-06-14ALSA: hda - Fix missing static inline to beep dummy functionTakashi Iwai
The commit 2308f4add3de9f6c9c9f02e49461e94d84bb200a missed static inline thus it resulted in multiple-definitions error at linking. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-06-13ALSA: hda - Fix beep_device compilation warningsJoe Perches
Using static inline functions can reduce compilation messages and macro misuse. sound/pci/hda/patch_conexant.c: In function ‘patch_cxt5045’: sound/pci/hda/patch_conexant.c:1232:3: warning: statement with no effect Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-11-16ALSA: hda - Fix beep_mode option valueTakashi Iwai
The beep_mode option value was wrongly defined: it must be 0 = off and 1 = on. Also, evaluate the beep_mode value at snd_hda_attach_beep_device() properly so that no device is created when beep_mode=0 is given. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-11-16ALSA: hda - add beep_mode module parameterJaroslav Kysela
The beep_mode parameter for snd-hda-intel module allows to choose among different digital beep device registation to the input layer. 0 = do not register to the input layer 1 = register to the input layer all time 2 = use "Beep Switch" control exported to user space mixer applications Also, introduce CONFIG_SND_HDA_INPUT_BEEP_MODE for default value.

2009-11-16ALSA: hda_intel: Digital PC Beep - delay input device unregistrationJaroslav Kysela
The massive register/unregister calls for input device layer might be overkill. Delay unregister call by one HZ as workaround. Also, as benefit, beep->enabled variable is changed immediately now (not from workqueue). Signed-off-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>
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>
2009-05-19ALSA: hda - Fix digital beep tone calculationTakashi Iwai
The digital beep tone is calculated in two different ways depending on the codec chip. The standard one is using a divider, and another one is a linear tone for IDT/STAC codecs. Currently, only the latter type is used for all codecs, which resulted in a wrong tone pitch. This patch adds the calculation of the standard HD-audio type. Also clean-up the fields in hda_beep struct. Reference: bko#13162 http://bugzilla.kernel.org/show_bug.cgi?id=13162 Signed-off-by: Takashi Iwai <tiwai@suse.de>

A digital beep generator can be used via input layer. Signed-off-by: Kusanagi Kouichi <slash@ma.neweb.ne.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-11-13ALSA: hda - Add digital beep playback switch for STAC/IDT codecsTakashi Iwai
The digital beep widget may have no mute control, and always enabling the beep is ofen pretty annoying, especially on laptops. This patch adds a mixer control "PC Beep Playback Switch" when there is no mixer amp mute is found, and controls it on software.
