The driver used to assume that the streaming endpoint's wMaxPacketSize
value would be an indication of how much data the endpoint expects or
sends, and compute the number of packets per URB using this value.However, the Focusrite Scarlett 2i4 declares a value of 1024 bytes,
while only about 88 or 44 bytes are be actually used. This discrepancy
would result in URBs with far too few packets, which would not work
correctly on the EHCI driver.To get correct URBs, use wMaxPacketSize only as an upper limit on the
packet size.Reported-by: James Stone

Patch fixes 6fire not to use stack as URB transfer_buffer. URB buffers need to
be DMA-able, which stack is not. Furthermore, transfer_buffer should not be
allocated as part of larger device structure because DMA coherency issues and
patch fixes this issue too.Cc: stable@vger.kernel.org

Commit 8f898e92aea2c24c7f379ee265d178f69ebb9c07 removed the redundant
reads of bInterfaceProtocol from the descriptors, but introduced a
regression to devices with quirks of type QUIRK_AUDIO_FIXED_ENDPOINT,
since fp->protocol is not set in setup process.As a consequence, audio streams would not get initialized, as the
following logs show:[ 48.923043] setting usb interface 3:1
[ 48.923056] Creating new capture data endpoint #81
[ 48.923484] 4:3:1: cannot set freq 48000 to ep 0x81This patch sets fp->protocol in create_fixed_stream_quirk() and
resolves the regression.Signed-off-by: Eldad Zack

This patch is adding extensive support (beside standard usb audio class)

- Access to AES bits (so now sending the IEC61937 compliant stream is
possible).
- Mixer SPDIF control added to turn on/off the optical transmitter.Signed-off-by: Przemek Rudy

The Roland Quad/Octo-Capture devices use some unknown vendor-specific

prevent the driver from attempting to use any other than the default
44.1 kHz sample rate, use quirks to hide the other alternate settings.Signed-off-by: Clemens Ladisch

snd_card_register() registers all devices newly added since the last
call. However, the playback/capture streams are handled as one ALSA
device, so the second /dev device will not be registered if the PCM
streams are added in two steps.QUIRK_AUTODETECT caused the probe callback to be called once for each
interface, which triggered this problem. Work around this by handling
this like the composite quirk, i.e., autodetecting all other interfaces
that might be used for PCM or MIDI.Signed-off-by: Clemens Ladisch

All the Roland/Edirol/BOSS USB audio devices that need implicit feedback
show this unambiguously in their descriptors, so it might be a good idea
to let the driver detect this.This should make playback work correctly (at least with Jack) with the
following devices:

- BOSS JS-8 Jam Station
- Edirol M-16DX
- Roland GAIA SH-01Signed-off-by: Clemens Ladisch

Instead of reading bInterfaceProtocol from the descriptor whenever it's
needed, store this value in the audioformat structure. Besides
simplifying some code, this will allow us to correctly handle vendor-

When the Android firmware enables the audio interfaces in accessory
mode, it always declares in the control interface's baInterfaceNr array
that interfaces 0 and 1 belong to the audio function. However, the
accessory interface itself, if also enabled, already is at index 0 and
shifts the actual audio interface numbers to 1 and 2, which prevents the
PCM streaming interface from being seen by the host driver.To get the PCM interface interface to work, detect when the descriptors
point to the (for this driver useless) accessory interface, and redirect
to the correct one.Reported-by: Jeremy Rosen

freqshift is only set for the data endpoint and syncmaxsize is only set
for the sync endpoint. This results in a syncmaxsize of zero used in the
proc output feedback format calculation, which gives a feedback format
incorrectly shown as 8.16 for UAC2 devices.As neither the data nor the sync endpoint gives all the relevant
content, output the two combined.Also remove the sync_endpoint "packet size" which is always zero
and the sync_endpoint "momentary freq" which is constant.Tested with UAC2 async and UAC1 adaptive, not tested with UAC1 async.

Current code does this:
be16_to_cpu(buf[i * 2] << 8 | buf[(i * 2) + 1])
Which is effectively (neglecting the index):
be16_to_cpu(be16_to_cpu(*((u16 *) buf)))
This means the int16 in the buffer is not converted at all.
Daniel Mack confirmed that the driver works on little endian
CPUs, leading to the conclusion that the device-side structure
is actually little endian.
This changes the code to use le16_to_cpu().Caught by sparse.

The recent changes in the USB API ("implement new semantics for
URB_ISO_ASAP") made the former meaning of the URB_ISO_ASAP flag the
default, and changed this flag to mean that URBs can be delayed.
This is not the behaviour wanted by any of the audio drivers because
it leads to discontinuous playback with very small period sizes.
Therefore, our URBs need to be submitted without this flag.Reported-by: Joe Rayhawk
