2012-10-31ALSA: hda - Fix silent headphone output from Toshiba P200Takashi Iwai
commit cb766404e6b8c566569eb9ada02ea45d28729864 upstream. By some reason, Toshiba laptop doesn't like the EAPD turned up for the headphone pin. Add a fix up code to force to turn down EAPD for NID 0x15.

commit 84f98fdf7865fbd35b312eb39ea91e5618c514c7 upstream. I have a Lenovo ThinkPad T430 and an UltraBase Series 3 docking station. Without this patch, if I plug my headphones into the jack on the computer, everything works fine. The computer speakers mute and the audio is played in the headphones. However, if I plug into the docking station headphone jack the computer speakers are muted but there is no audio in the headphones.

commit d17344b3547669f5b6ee4fda993d03737a141bd6 upstream. There was a race condition when the system suspends while hda_power_work is running in the work queue. If system suspend (snd_hda_suspend) happens after the work queue releases power_lock but before it calls hda_call_codec_suspend, codec_suspend runs with power_on=0, causing the codec to power up for register reads, and hanging when it calls cancel_delayed_work_sync from the running work queue. The call chain from the work queue will look like this: hda_power_work <<- power_on = 1, unlock, then power_on cleard by suspend hda_call_codec_suspend hda_set_power_state snd_hda_codec_read codec_exec_verb snd_hda_power_up snd_hda_power_save __snd_hda_power_up cancel_delayed_work_sync <<-- cancelling executing wq Fix this by waiting for the work queue to finish before starting suspend if suspend is not happening on the work queue.

2012-10-13ALSA: snd-usb: Add quirks for Playback Designs devicesDaniel Mack
commit 2b58fd5b3193fd3af3d15114d95706087d25a7fe upstream. Playback Designs' USB devices have some hardware limitations on their USB interface. In particular: - They need a 20ms delay after each class compliant request as the hardware ACKs the USB packets before the device is actually ready for the next command. Sending data immediately will result in buffer overflows in the hardware. - The devices send bogus feedback data at the start of each stream which confuse the feedback format auto-detection. This patch introduces a new quirks hook that is called after each control packet and which adds a delay for all devices that match Playback Designs' USB VID for now. In addition, it adds a counter to snd_usb_endpoint to drop received packets on the floor. Another new quirks function that is called once an endpoint is started initializes that counter for these devices on their sync endpoint.

commit cf55e904516947597d75fd3844acc24891a95772 upstream. If headphone jack can't detect plug presence, and we have the jack in the jack table, snd_hda_jack_detect will return the plug as always present (as it'll be considered as a phantom jack). The problem is that when this happens, line out pins will always be disabled, resulting in no sound if there are no headphones connected. This was reported as a no sound problem after suspend on http://bugs.launchpad.net/bugs/1052499, since the bug doesn't manifests on first initialization before the phantom jack is added, but on resume we reexecute the initialization code, and via_hp_automute starts reporting HP always present with the jack now on the table.

commit d4f1e48bd11e3df6a26811f7a1f06c4225d92f7d upstream. When the loopback timer handler is running, calling del_timer() (for STOP trigger) will not wait for the handler to complete before deactivating the timer. The timer gets rescheduled in the handler as usual. Then a subsequent START trigger will try to start the timer using add_timer() with a timer pending leading to a kernel panic.

However, it's the place just after codec free callback, thus no codec callbacks should be called after that. On a codec like CS4206, it results in Oops due to the access in init callback.

2012-09-06ALSA: usb-audio: Fix bogus error messages for delay accountingTakashi Iwai
The recent fix for the missing fine delayed time adjustment gives strange error messages at each start of the playback stream, such as delay: estimated 0, actual 352 delay: estimated 353, actual 705 These come from the sanity check in retire_playback_urb(). Before the stream is activated via start_endpoints(), a few silent packets have been already sent. And at this point the delay account is still in the state as if the new packets are just queued, so the driver gets confused and spews the bogus error messages. For fixing the issue, we just need to check whether the received packet is valid, whether it's zero sized or not.

2012-09-06ASoC: samsung dma - Don't indicate support for pause/resume.Dylan Reid
The pause and resume operations indicate that the stream can be un-paused/resumed from the exact location they were paused/suspended. This is not true for this driver, the pause and suspend triggers share the same code path with stop, they flush all pending DMA transfers. This drops all pending samples. The pause_release/resume triggers are the same as start, except that prepare won't be called beforehand, nothing will be enqueued to the DMA engine and nothing will happen (no audio). Removing the pause flag will let apps know that it isn't supported. Removing the resume flag will cause user space to call prepare and start instead of resume, so audio will continue playing when the system wakes up. Before removing the pause and resume flags, I tested this on an exynos 5250, using 'aplay -i'. Pause/un-pause leads to silence followed by a write error. Suspend/resume testing led to the same result. Removing the two flags fixes suspend/resume (since snd_pcm_prepare is called again). And leads to a proper reporting of pause not supported.

2012-08-31ALSA: snd-usb: fix cross-interface streaming devicesDaniel Mack
Commit 68e67f40b ("ALSA: snd-usb: move calls to usb_set_interface") saved us some unnecessary calls to snd_usb_set_interface() but ignored the fact that there is at least one device out there which operates on two endpoint in different interfaces simultaniously. Take care for this by catching the case where data and sync endpoints are located on different interfaces and calling snd_usb_set_interface() between the start of the two endpoints.

2012-08-31ALSA: snd-usb: fix calls to next_packet_sizeDaniel Mack
In order to support devices with implicit feedback streaming models, packet sizes are now stored with each individual urb, and the PCM handling code which fills the buffers purely relies on the size fields now. However, calling snd_usb_audio_next_packet_size() for all possible packets in an URB at once, prior to letting the PCM code do its job does in fact not lead to the same behaviour than what the old code did: The PCM code will break its loop once a period boundary is reached, consequently using up less packets that it really could. As snd_usb_audio_next_packet_size() implements a feedback mechanism to the endpoints phase accumulator, the number of calls to that function matters, and when called too often, the data rate runs out of bounds. Fix this by making the next_packet function public, and call it from the PCM code as before if the packet data sizes are not defined.

2012-08-31ALSA: snd-usb: restore delay informationDaniel Mack
Parts of commit 294c4fb8 ("ALSA: usb: refine delay information with USB frame counter") were unfortunately lost during the refactoring of the snd-usb driver in 3.5. This patch adds them back, restoring the correct delay information behaviour.

2012-08-30ALSA: snd-usb: Fix URB cancellation at stream startDaniel Mack
Commit e9ba389c5 ("ALSA: usb-audio: Fix scheduling-while-atomic bug in PCM capture stream") fixed a scheduling-while-atomic bug that happened when snd_usb_endpoint_start was called from the trigger callback, which is an atmic context. However, the patch breaks the idea of the endpoints reference counting, which is the reason why the driver has been refactored lately. Revert that commit and let snd_usb_endpoint_start() take care of the URB cancellation again. As this function is called from both atomic and non-atomic context, add a flag to denote whether the function may sleep.

2012-08-28sound: tegra_alc5632: remove HP detect GPIO inversionStephen Warren
Both the schematics and practical testing show that the HP detect GPIO is high when the headphones are plugged in. Hence, the snd_soc_jack_gpio should not specify to invert the signal.
