The flag bus->shutdown implies that the control elements might have been already destroyed. When a codec is resumed at this state and tries to call vmaster hook (e.g. in snd_hda_gen_init()), it would refer to a non-existing object, resulting in Oops in the end. This patch just adds a check of the flag in the caller side for avoiding such a crash. Though, the best would be to clear hook->sw_kctl by the destructor of the corresponding ctl element, but vmaster uses its own private_free, it can't be done easily. So let it be for a while.

When graphics initializes the HDMI chip, sometimes this leads to pins going into D3 and right channel being muted. If the audio driver finishes initialization before the graphic driver does, this situation becomes permanent. This is a workaround that checks for this situation and corrects it on playback prepare. It has been verified working on at least one machine.

When setting up the aamix output paths, use the primary DAC instead of the individual DAC for each output as default. Otherwise multiple DACs will be turned on for a single aamix widget, which results in doubly or more volumes, because the duplicated signals will be sent through all these DACs for a single stream.

When we have a loopback mixer control, this should manage the state whether the output paths include the aamix or not. But the current code blindly initializes the output paths with aamix = true, thus the aamix is enabled unless the loopback mixer control is changed. Also, update_aamix_paths() called by the loopback mixer control put callback invokes snd_hda_activate_path() with aamix = true even for disabling the mixing. This leaves the aamix path even though the loopback control is turned off. This patch fixes these issues: - Introduced aamix_default() helper to indicate whether with_aamix is true or false as default - Fix the argument in update_aamix_paths() for disabling loopback Reported-by: Lydia Wang <LydiaWang@viatech.com.cn> Cc: <stable@vger.kernel.org> [v3.9+] Signed-off-by: Takashi Iwai <tiwai@suse.de>

For capture, the delay through the codec contributes to the time stamp of the sample recorded at the A to D. Rename the codec time stamp function appropriately. Signed-off-by: Dylan Reid <dgreid@chromium.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

ASoC: Updates for v3.10 A bunch of changes here, the most interesting one subsystem wise being Morimoto-san's work to create snd_soc_component which doesn't do much for now but will be pretty important going forwards: - Add a new component object type which will form the basis of moving to a more generic handling of SoC and off-SoC components, contributed by Kuninori Morimoto. - A fairly large set of cleanups for the dmaengine integration from Lars-Peter Clausen, starting to move towards being able to have a generic driver based on the library. - Performance optimisations to DAPM from Ryo Tsutsui. - Support for mixer control sharing in DAPM from Stephen Warren. - Multiplatform ARM cleanups from Arnd Bergmann. - New CODEC drivers for AK5385 and TAS5086 from Daniel Mack.

Commit 88a8516a (ALSA: usbaudio: implement USB autosuspend) introduced autopm for all USB audio/MIDI devices. However, many MIDI devices, such as synthesizers, do not merely transmit MIDI messages but use their MIDI inputs to control other functions. With autopm, these devices would get powered down as soon as the last MIDI port device is closed on the host. Even some plain MIDI interfaces could get broken: they automatically send Active Sensing messages while powered up, but as soon as these messages cease, the receiving device would interpret this as an accidental disconnection. Commit f5f16541 (ALSA: usb-audio: Fix missing autopm for MIDI input) introduced another regression: some devices (e.g. the Roland GAIA SH-01) are self-powered but do a reset whenever the USB interface's power state changes. To work around all this, just disable autopm for all USB MIDI devices.

With this patch, a TRRS headset mic cannot be successfully detected on the Asus X101CH, and we can also distinguish between headphone and headset automatically.

On some machines, there is a headset jack that can support both headphone, headsets (of both CTIA and OMTP type) and mic-in. On other machines, the headset jack supports headphone, headsets (both CTIA and OMTP), but not mic-in. This patch implements that functionality as different capture sources.

When recording at 176.2KHz or 192Khz, the device adds a 32-bit length header to the capture packets, which obviously needs to be ignored for recording to work properly. Userspace expected: L0 L1 L2 R0 R1 R2 ...but actually got: R2 L0 L1 L2 R0 R1 Also, the last byte of the length header being interpreted as L0 of the first sample caused spikes every 0.5ms, resulting in a loud 16KHz tone (about the highest 'B' on a piano) being present throughout captures. Tested at all sample rates on an E-Mu 0404USB, and tested for regressions on a generic USB headset.
