* modem.conf Off-hook improve behaviorDavid Fries2010-01-223-1/+24
| | | | | | | | | | | | | | | Only restore the old value if it differs from the requested value, because if it has changed restoring the old value overrides the change. Take for example, a voice modem with a .conf that sets preserve off-hook. Start playback (on-hook to off-hook), start record (off-hook to off-hook), stop playback (off-hook to restore on-hook), stop record (on-hook to restore off-hook), Clearly you don't want to leave the modem "on the phone" now that there isn't any playback or recording active.

* pcm: Close event timer in pcm_hw pluginJaroslav Kysela2009-12-211-12/+14
| | | | | | | | | | | | Dan McCombs discovered that snd_pcm_close() invocations are not leading to associated timers being closed, which results in successively more timers being created but not freed.

| | | | | | | | | | | list->card is wrongly assumed to be initialized, but the previous initialization is within a conditional that is false when only card-independent devices are found.

* Fix corruption after snd_device_name_hint()Takashi Iwai2009-11-031-1/+4
| | | | | | | | | | | | | | | | | | snd_device_name_hint() corrupts the config name space after its call. This results in the error from the suceeding calls of snd_pcm_open() after snd_device_name_hint(). The bug is in try_config() in namehint.c; it calls snd_config_delete(res) but res can be two different objects in the function. One is the object obtained via snd_config_search_definition(), and another is the one from snd_config_search_alias_hooks(). The former is the expanded objects, thus it should be freed. But, the latter is a reference, and must not be freed. This patch adds the check to free or not. Reported-by: John Lindgren <john.lindgren@tds.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* dmix - Fix snd_pcm_info()Takashi Iwai2009-09-281-1/+4
| | | | | | | | Call the slave snd_pcm_info() as long as possible in the direct plugins (i.e. when the PCM device could be opened with O_APPEND mode). This allows dmix/dsnoop as a salve for PCM hook controls. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* pcm_hw: Always use delay ioctl in snd_pcm_delay()Kai Vehmanen2009-09-111-22/+0
| | | | | | | | | | | | | As the result of snd_pcm_delay() is affected not only by hw_ptr and appl_ptr, but also by 'runtime->delay' property, either SNDRV_PCM_IOCTL_DELAY or SNDRV_PCM_IOCTL_STATUS ioctl must be used to get the correct result. Previously 'runtime->delay' was ignored in case 'hw->sync_ptr' was used. Signed-off-by: Kai Vehmanen <kvehmanen@eca.cx> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* PCM - Change the hw_params determination orderTakashi Iwai2009-09-091-9/+24
| | | | | | | | | | | | | In snd_pcm_hw_params_choose(), set the buffer size before the period size and time as default. This will give more useful configuration for most of apps, i.e. larger buffer size. For apps that require the old behavior, now the function checks the environment variable $LIBASOUND_COMPAT. If this variable is set to non-empty, the hw_params is determined in the old way, first period then buffer sizes. Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | This reverts commit 96da0c842d14b40ce8e37726b259229634b3aa21. This way of fix brokes card-specific configuration loading. See http://bugzilla.redhat.com bug#521988 for details.

* pcm: workaround for avoiding automatic start in mmap modeTakashi Iwai2009-08-211-5/+29
| | | | | | | | | | | | | | | | In the normal mmap mode, the stream isn't started automatically even after the data >= start_threshold has been written. However, in the mmap-emulation mode, the stream is started because it uses snd_pcm_write_areas() internally. As a workaround for this inconsistency, start_threshold value is changed dynamically in sw_parmams and mmap_commit callbacks in mmap-emul plugin. Meanwhile, start_threshold for slave PCM is set to boundary so that only this plugin (or the one over it) can control the start of the stream. This will fix problems in some apps using pulse plugin in the mmap mode. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* Fix driver conf parsing in snd_config_hook_load_for_all_cards()Takashi Iwai2009-08-101-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reported by Kevin Goodsell. Summary: load_for_all_cards fails with existing configuration elements In snd_config_hook_load_for_all_cards, the first call to snd_config_search attempts to locate an existing configuration node with the name of the driver. Typically none is found, and everything is good. However, if such a node is located, the next line assumes it is a leaf node with type 'string' and calls snd_config_get_string to fetch the string value. If this fails, the entire hook is abandoned. Because of this, setting something like the following in asoundrc: cards.<driver name>.foo 0 is sufficient to disable the entire card-specific configuration. As a concrete example, I have a HDA-Intel sound card. dmix.conf includes a way to set period_size, period_time, and periods by using configuration elements of the form cards.<driver name>.pcm.dmix.<var>. In ~/.asoundrc I add cards.HDA-Intel.pcm.dmix.period_size 1024 This will cause HDA-Intel.conf to fail to load, and the pcm defined in default.conf will fail to find the device-specific pcm cards.HDA-Intel.pcm.default, and fall back on the default pcm using plughw. By attempting to configure dmix, I have disabled it. Signed-off-by: Takashi Iwai <tiwai@suse.de>
