2010-02-23ALSA: usbaudio: consolidate header filesDaniel Mack6-216/+121
Use the definitions from linux/usb/audio.h all over the ALSA USB audio driver and add some missing definitions there as well. Use the endpoint attribute macros from linux/usb/ch9 and remove the own things from sound/usb/usbaudio.h. Now things are also nicely prefixed which makes understanding the code easier.

2010-02-23ALSA: usbmixer: bail out early when parsing audio class v2 descriptorsDaniel Mack1-1/+12
This is just a quick hack that needs to be removed once the new units defined by the audio class v2.0 standard are supported. However, it allows using these devices for now, without mixer support. Signed-off-by: Daniel Mack <daniel@caiaq.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2010-02-23ALSA: usbaudio: implement basic set of class v2.0 parserDaniel Mack2-63/+292
This adds a number of parsers for audio class v2.0. In particular, the following internals are different and now handled by the code: * the number of streaming interfaces is now reported by an interface association descriptor. The old approach using a proprietary descriptor is deprecated. * The number of channels per interface is now stored in the AS_GENERAL descriptor (used to be part of the FORMAT_TYPE descriptor). * The list of supported sample rates is no longer stored in a variable length appendix of the format_type descriptor but is retrieved from the device using a class specific GET_RANGE command. * Supported sample formats are now reported as 32bit bitmap rather than a fixed value. For now, this is worked around by choosing just one of them. * A devices needs to have at least one CLOCK_SOURCE descriptor which denotes a clockID that is needed im the class request command. * Many descriptors (format_type, ...) have changed their layout. Handle this by casting the descriptors to the appropriate structs. Signed-off-by: Daniel Mack <daniel@caiaq.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2010-02-23ALSA: usbaudio: introduce new types for audio class v2Daniel Mack2-10/+23
This patch adds some definitions for audio class v2. Unfortunately, the UNIT types PROCESSING_UNIT and EXTENSION_UNIT have different numerical representations in both standards, so there is need for a _V1 add-on now. usbmixer.c is changed accordingly.

2010-02-23ALSA: usbaudio: parse USB descriptors with structsDaniel Mack2-95/+140
In preparation of support for v2.0 audio class, use the structs from linux/usb/audio.h and add some new ones to describe the fields that are actually parsed by the descriptor decoders. Also, factor out code from usb_create_streams(). This makes it easier to adopt the new iteration logic needed for v2.0.

2010-02-16ALSA: USB MIDI support for Access Music VirusTISebastien Alaiwan3-0/+65
Here's a patch that adds MIDI support through USB for one of the Access Music synths, the VirusTI. The synth uses standard USBMIDI protocol on its USB interface 3, although it does signal "vendor specific" class. A magic string has to be sent on interface 3 to enable the sending of MIDI from the synth (this string was found by sniffing usb communication of the Windows driver). This is all my patch does, and it works on my computer. Please note that the synth can also do standard usb audio I/O on its interfaces 2&3, which already works with the current snd-usb-audio driver, except for the audio input from the synth. I'm going to work on it when I have some time.

2010-01-18ALSA: pcm - Call pgprot_noncached() for vmalloc'ed buffersTakashi Iwai2-0/+4
pgprot_noncached() can be set for vmalloc'ed buffers safely, and we'd need non-cached behavior more or less, even for the intermediate ring- buffers. Now snd_pcm_lib_mmap_vmalloc() is added as the common PCM mmap callback that is coupled with snd_pcm_lib_alloc_vmalloc_buffer() & co. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-12-28ALSA: usb-audio: relax urb data align. restriction HVR-950Q and HVR-850 onlyJohn S. Gruber2-2/+30
Addressing audio quality problem. In sound/usb/usbaudio.c, for the Hauppage HVR-950Q and HVR-850 only, change retire_capture_urb to allow transfers on audio sub-slot boundaries rather than audio slots boundaries. With these devices the left and right channel samples can be split between two different urbs. Throwing away extra channel samples causes a sound quality problem for stereo streams as the left and right channels are swapped repeatedly, perhaps many times per second. Urbs unaligned on sub-slot boundaries are still truncated to the next lowest stride (audio slot) to retain synchronization on samples even though left/right channel synchronization may be lost in this case. Detect the quirk using a case statement in snd_usb_audio_probe. BugLink: https://bugs.launchpad.net/ubuntu/+bug/495745 Signed-off-by: John S.

2009-12-28ALSA: usb-audio: make buffer pointer based on bytes instead on framesClemens Ladisch1-39/+37
Since there are devices that do not align the size of their data packets to frame boundaries, the driver needs to be able to keep track of partial frames.

2009-11-07ALSA: usb-audio: fix combine_word problemJulian Anastasov1-1/+1
Fix combine_word problem where first octet is not read properly. The only affected place seems to be the INPUT_TERMINAL type. Before now, sound controls can be created with the output terminal's name which is a fallback mechanism used only for unknown input terminal types. For example, Line can wrongly appear as Speaker. After the change it should appear as Line. The side effect of this change can be that users can expect the wrong control name in their scripts or programs while now we return the correct one. Probably, these defines should use get_unaligned_le16 and friends. Signed-off-by: Julian Anastasov <ja@ssi.bg> Cc: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
