2014-12-18ALSA: usb-audio: extend KEF X300A FU 10 tweak to Arcam rPACJiri Jaburek1-3/+12
The Arcam rPAC seems to have the same problem - whenever anything (alsamixer, udevd, 3.9+ kernel from 60af3d037eb8c, ..) attempts to access mixer / control interface of the card, the firmware "locks up" the entire device, resulting in SNDRV_PCM_IOCTL_HW_PARAMS failed (-5): Input/output error from alsa-lib. Other operating systems can somehow read the mixer (there seems to be playback volume/mute), but any manipulation is ignored by the device (which has hardware volume controls).

This makes the midi interface and capture work out of the box with R16 (and presumably R24 too but untested). Playback stream would also seem to function fine except for one caveat: no sound is produced, so it is disabled for now.

2014-11-28ALSA: usb-audio: Add mode select quirk for Denon/Marantz DACsJurgen Kramer3-0/+46

2014-11-21ALSA: usb-audio: Add resume support for Scarlett mixersTakashi Iwai1-14/+51
Scarlett driver uses almost compatible usb_mixer_elem_info struct, so we just need to add a couple of simple resume callbacks to handle them accordingly. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-11-21ALSA: usb-audio: Add resume support for MicroII SPDIF ctlsTakashi Iwai1-42/+93

2014-11-21ALSA: usb-audio: Add resume support for FTU controlsTakashi Iwai1-140/+54
A few FTU mixer controls have the own value handling, so they have to be rewritten to follow the support for resume callbacks. This ended up in a fair amount of refactoring. Its own struct is now removed, instead the values are embedded in kctl private_value totally. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-11-21ALSA: usb-audio: Add resume support for Native Instruments controlsTakashi Iwai1-47/+52
The changes at this time are a bit more wider than previous ones. Firstly, the NI controls didn't cache the values, so I had to implement the caching. It's stored in bit 24 of private_value. In addition to that, the initial values have to be read from registers. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2014-11-21ALSA: usb-audio: Add audigy2nx resume supportTakashi Iwai2-57/+92
Rewrite the code to handle LEDs on audigy2nx and co for supporting the proper resume. A new internal helper function add_single_ctl_with_resume() is introduced to manage the usb_mixer_elem_list more easily. Also while we're at it, move audigy2nx_leds[] in usb_mixer_interface struct into the private_value of each kctl, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-11-21ALSA: usb-audio: Allow quirks to handle own resume and proc dumpTakashi Iwai4-88/+114
So far, we blindly assumed that the all usb-audio mixer elements follow the standard and apply the standard resume method for the registered elements in the id_elems[] list. However, some quirks really need the own resume and it's incomplete for now. This patch enhances the resume handling in two folds: - split some fields in struct usb_mixer_elem_info into a smaller header struct (usb_mixer_elem_list) for keeping the minimal information in the linked-list; the usb_mixer_elem_info embeds this header struct instead - add resume and dump callbacks to usb_mixer_elem_list struct to allow quirks providing the own methods For the standard mixer elements, these new callbacks are set to the standard ones as default, thus there is no functional change by this patch yet. The dump and resume callbacks are typedef'ed for ease of later patches using arrays of such function pointers. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-11-20ALSA: usb-audio: Refactor ignore_ctl_error checksTakashi Iwai1-23/+16
Introduce an internal helper macro for avoiding many open codes. The only slight behavior change is in a couple of get ballcks where the value is reset at error no matter whether ignore_ctl_error is set or not. Actually this is even safer than before. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2014-11-16ALSA: usb-audio: Add ctrl message delay quirk for Marantz/Denon devicesJurgen Kramer1-0/+14
This patch adds a USB control message delay quirk for a few specific Marantz/Denon devices. Without the delay the DACs will not work properly and produces the following type of messages: Nov 15 10:09:21 orwell kernel: [ 91.342880] usb 3-13: clock source 41 is not valid, cannot use Nov 15 10:09:21 orwell kernel: [ 91.343775] usb 3-13: clock source 41 is not valid, cannot use There are likely other Marantz/Denon devices using the same USB module which exhibit the same problems. But as this cannot be verified I limited the patch to the devices I could test.

2014-11-13ALSA: usb-audio: Scarlett mixer interface for 6i6, 18i6, 18i8 and 18i20Chris J Arges4-0/+983
This code contains the Scarlett mixer interface code that was originally written by Tobias Hoffman and Robin Gareus. Because the device doesn't properly implement UAC2 this code adds a mixer quirk for the device. Changes from the original code include removing the metering code along with dead code and comments. Compiler warnings were fixed. The code to initialize the sampling rate was causing a crash this was fixed as discussed on the mailing list. Error, and info messages were convered to dev_err and dev_info interfaces. The custom scarlett_mixer_elem_info struct was replaced with the more generic usb_mixer_elem_info to be able to recycle more code from mixer.c. This patch also makes additional modifications based on upstream comments. Individual control creation functions are removed and a generic function is no used. Macros for function calls are removed to improve readability. Hardcoded control initialization is removed. Save to HW functionality has been removed. Strings for enums are created dynamically for the mixer. Strings used for controls are now SNDRV_CTL_ELEM_ID_NAME_MAXLEN length.

2014-11-11ALSA: usb-audio: Add duplex mode for Digidesign Mbox 1 and enable mixerDamien Zammit1-9/+32
This patch provides duplex support for the Digidesign Mbox 1 sound card and has been a work in progress for about a year. Users have confirmed on my website that previous versions of this patch have worked on the hardware and I have been testing extensively. It also enables the mixer control for providing clock source selector based on the previous patch. The sample rate has been hardcoded to 48kHz because it works better with the S/PDIF sync mode when the sample rate is locked. This is the highest rate that the device supports and no loss of functionality is observed by restricting the sample rate apart from the inability to selec a lower rate.

Currently the composite quirk doesn't work when multiple entries are assigned to the same interface because it marks the interface as claimed then checks whether the interface has been already claimed for the secondary entry. But, if you look at the code, you'll notice that multiple entries are allowed if the entry is the current interface; i.e. the current behavior is anyway inconsistent, and this is an unintended shortcoming. This patch fixes the problem by marking the relevant interfaces as claimed after applying the all composite entries. This fix will be needed for the upcoming enhancements for Digidesign Mbox 1 quirks. Reviewed-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-11-09ALSA: pcm: Add snd_pcm_stop_xrun() helperTakashi Iwai4-37/+11
Add a new helper function snd_pcm_stop_xrun() to the standard sequnce lock/snd_pcm_stop(XRUN)/unlock by a single call, and replace the existing open codes with this helper. The function checks the PCM running state to prevent setting the wrong state, too, for more safety. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-11-06ALSA: usb-audio: Trigger PCM XRUN at XRUNTakashi Iwai1-3/+8
The usb-audio driver detects XRUN at its complete callback, but the actual code to trigger PCM XRUN is commented out because it caused deadlock in the past. This patch revives the PCM trigger properly. It resulted in more than just enabling snd_pcm_stop(), but it had to deduce the PCM substream with proper NULL checks and holds the stream lock around the call.

When a device has both audio and midi interfaces, it gets called twice, and currently the driver tries to release resources at the last call. At this point, the first parent interface has been already deleted, thus deleting a child of the first parent hits such a warning. For fixing this problem, we need to call snd_card_disconnect() and cancel pending operations at the very first disconnect while the release of the whole objects waits until the last disconnect call.

2014-11-04ALSA: usb-audio: Pass direct struct pointer instead of list_headTakashi Iwai5-21/+15
Some functions in mixer.c and endpoint.c receive list_head instead of the object itself. This is not obvious and rather error-prone. Let's pass the proper object directly instead. The functions in midi.c still receive list_head and this can't be changed since the object definition isn't exposed to the outside of midi.c, so left as is.

2014-11-04ALSA: usb-audio: Flatten probe and disconnect functionsTakashi Iwai1-45/+30
The usb-audio probe and disconnect functions have been split just for adapting the (new!) API at 2.5 kernel time. We left them until now, partly because we wanted to build with the pretty old kernels in the external alsa-driver tree. But the support of such old kernels has been longly stopped, so it's good time to clean up this mess. One good point by this cleanup is that now the probe function returns a proper error code instead of only -EIO. Signed-off-by: Takashi Iwai <tiwai@suse.de>
