In the commit [fa4f18b4: ALSA: hda - Refresh widgets sysfs at probing Haswell+ HDMI codecs], snd_hdac_refresh_widget_sysfs() is explicitly called in the codec driver. But this results in refreshing twice, as snd_hdac_refresh_widget_sysfs() itself calls snd_hdac_refresh_widgets() function. Instead, we can replace the call in snd_hda_codec_update_widgets() with snd_hdac_refresh_widget_sysfs(). This also fixes the missing sysfs update for ca0132, too. Signed-off-by:

The widget power-saving code tries to turn up/down the power of each widget in the I/O paths that are modified at each jack plug/unplug. The recent report revealed that the power activation leaves some widgets unpowered after plugging. This is because snd_hda_activate_path() turns on path->active flag at the end of the function while the path power management is done before that. Then it's regarded as if nothing is active, and the driver turns off the power. The fix is simply to set the flag at the beginning of the function, before trying to power up.

The is_active_nid_for_any() function in the generic parser is supposed to check all connections from/to the given widget, but the current code checks only the first input connection (index = 0). This patch corrects the code to check all inputs by passing -1 to index argument. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=102521 Cc: <stable@vger.kernel.org> [v4.1+] Signed-off-by:

After a for-loop was replaced by list_for_each_entry, see Commit bbbc7e85 ("ALSA: hda - Allocate hda_pcm objects dynamically"), Commit 751e2216 ("ALSA: hda: fix possible null dereference"), a possible NULL pointer dereference has been introduced; this patch adds the NULL check on pcm->pcm, while leaving a potentially superfluous check on pcm itself untouched.

The drivers need to set the spib and maxfifios values, so add these new APIs snd_hdac_ext_stream_set_spib() and snd_hdac_ext_stream_set_spbmaxfifo() APIs For these APIs we also need to have spib and fifos pointer, so add these to hdac_ext_stream and initialize them at stream init Signed-off-by:

Convert the ac97_bus from legacy suspend/resume callbacks to dev_pm_ops. Since there isn't anything special to do at the bus level the bus driver does not have to implement any callbacks. The device driver core will automatically pick up and execute the device's PM ops. As there is only a single AC'97 driver implementing suspend and resume, update both the core and driver at the same time to avoid unnecessary code churn. While we are at it also drop the ifdefs around the suspend/resume functions to increase compile test coverage. Signed-off-by:

Intel Haswell (and later) codec refreshes the widgets tree to expose the whole widget nodes at probing. However, this refresh was missing for sysfs tree. This patch adds the missing piece, as we have now a proper API. Reported-by:

I believe this probably cannot happen, as the code suggests. There would have to be an kcontrol->index.id which was zero, otherwise this would be prevented in snd_ctl_find_id(). But snd_BUG_ON() is just a WARN() or a no-op so static checkers complain that we keep on going with a negative offset. Let's just handle the error as well as printing a warning. Signed-off-by:

Some codecs like Intel HDMI by default do not show up all the pins, they have to be manually enabled, so we need to refresh the codec widgets and then recreate the sysfs tree. So add new API snd_hdac_refresh_widget_sysfs() to do this. It should be be used by codec driver after sending magic verbs to codec Signed-off-by:

On shutdown/reboot of CX20722, first shut down all EAPDs, then shut down the afg node to D3. Failure to do so can lead to spurious noises from the internal speaker directly after reboot (and before the codec is reinitialized again, i e in BIOS setup or GRUB menus).

Merge tag 'asoc-v4.2-disable-topology' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Disable topology support for v4.2 The topology code merged in the v4.2 merge window introduced a new ABI which was believed to be suitable for use but subsequently additional work by the developers of this feature have revealed some problems that need to be addressed. In order to allow this to be done without having to support the initial ABI add Kconfig to disable the build and also add some #error statements to the UAPI header so users can't use them.

The input terminal parser recurses into the referenced clock entity to verify it is existant and thus the terminal descriptor is valid. The actual property values of the term instance which is initially parsed must not be overriden by the recursion. For this to work the term properties have to be assigned after recursing into the referenced clock entity descriptors. Signed-off-by:

The fix for deadlock in PM in commit [1ee23fe0: ALSA: usb-audio: Fix deadlocks at resuming] introduced a new check of in_pm flag. However, the brainless patch author evaluated it in a wrong way (logical AND instead of logical OR), thus usb_autopm_get_interface() is wrongly called at probing, leading to unbalance of runtime PM refcount. This patch fixes it by correcting the logic. Reported-by:

Since the topology API is still in sufficient flux for changes to be identified disable the use of the userspace ABI by adding #error statements to the code, ensuring that nobody relies on the headers as currently defined.

Allow the topology code to be compiled out so that users who don't need topology don't need to havve the code compiled in, saving them some memory. Some more configuration could be added to remove some of the hooks into the core data structures but that is probably best done with some refactoring to use functions to do the updates of the data structures rather than ifdefing in the code as we'd need to do at the minute.

The M-Audio Transit exposes an interface with a SYNC_NONE attribute. This is not a valid value according to the USB audio classspec. However there is a sync endpoint associated to this record. Changing the logic to try to use this sync endpoint allows for seamless transitions between altset 2 and altset 3.

USB Audio Class version 2.0 supports three different parameter block sizes for CUR requests, which are 1 byte (5.2.3.1 Layout 1 Parameter Block), 2 bytes (5.2.3.2 Layout 2 Parameter Block) and 4 bytes (5.2.3.3 Layout 3 Parameter Block).

Alienware 15 has CA0132 codec for its onboard sound, but the pin config and mapping seem quite different from other Creative boards. This patch corrects them, at least, for providing the right headphone and mic jack notification, as well as removing the non-existing SPDIF pins. Even with this fix, not all stuff works perfectly yet, mainly because of the badly written ca0132 driver code -- it has too many implicit assumptions of pin configs and maps. Nevertheless, this is a small good step forward. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=101981Signed-off-by:

The echoaudio locally defines TRUE and FALSE. Not only is this redundant given that C now has a boolean type it results in lots of warnings as other headers also define these macros, causing duplicate definitions. Fix this by removing the local defines and converting all local users to use the standard C true and false instead, simply removing the macros is less safe due to implicit inclusion of the other definitons.
