Subject: ALSA: preliminary support for Toshiba SB-0500

The Toshiba Multimedia Center SB-0500 is a rebranded version of the
Creative Technology SB Live! 24-bit External: it shares the same chipset
and only has minor cosmetic differences. Remote controller works with
alsa_usb module, basic audio is there and mixer controls are mostly
untested.

Subject: ALSA: USB quirk for Logitech Quickcam Pro 9000 name

The Logitech QuickCam Pro 9000 does not appear to any product identification
strings in its USB device descriptor. Therefore it receives a device name of
"USB Device 0x46d:0x990". Th e attached patch below adds a USB quirk to
provide a more friendly name.

Subject: ALSA: usb-audio - Quirk for Serato phono

Ignore errors (wrong usb interface data) found when using the serato
scratch live box with alsa

Thus the alsa controls can be accessed (beware: they don't work though -
but at least it's one ugly error message less)

Subject: sound: usb-audio: use normal number of frames for no-data URBs

When sending a silence URB (before playback has started, or when it is
paused), use the number of frames that would be normally sent instead of
a single frame so that the rate at which completion interrupts arrive is
consistent.

Subject: sound: usb-audio: limit playback queue length

Once our URBs contain enough packets, queueing more URBs does not give
us any additional underrun protection (as we use double-buffering) but
just increases latency unnecessarily.  Therefore, we try to limit the
queue length to some reasonable value.

Subject: sound: usb-audio: make URB sizes more equal

Distribute the packets evenly among the URBs, instead of making all URBs
except the last one to have the maximum size.  This makes the timing of
pointer updates more regular and removes some special cases from the
code.

Subject: sound: usb-audio: handle wMaxPacketSize for FIXED_ENDPOINT devices

For audio devices that do not have proper audio descriptors (e.g.,
Edirol UA-20), we use hardcoded parameters from our quirks list.
However, we must still read the maximum packet size from the standard
endpoint descriptor; otherwise, we might use packets that are too big
and therefore rejected by the USB core.

Subject: sound: usb-audio: fix uninitialized variable with M-Audio MIDI
 interfaces

Fix the snd_usbmidi_create_endpoints_midiman() function, which forgot to
set the out_interval member of the endpoint info structure for Midiman/
M-Audio devices.  Since kernel 2.6.24, any non-zero value makes the
driver use interrupt transfers instead of bulk transfers.  With EHCI
controllers, these random interval values result in unbearably large
latencies for output MIDI transfers.

The CM6207 incorrectly advertises its 96 kHz playback setting as 48 kHz
in its USB device descriptor. This patch extends an existing workaround
in usbaudio.c to also cover the CM6207.

This resolves issue 0004249 in the ALSA bug tracker.

Subject: sound: usb-audio: fix rules check for 32-channel devices

When storing the channel numbers used by a format, and if the device
happens to support 32 channels, the code would try to store 1<<32 in
a 32-bit value.

Since no valid format can have zero channels, we can use 1<<(channels-1)
instead of 1<<channels so that all the channel numbers that we test for
fit into 32 bits.

Subject: sound: usb-audio: fix queue length check for high speed devices

When checking for the maximum queue length, we have to take into account
that MAX_QUEUE is measured in milliseconds (i.e., frames) while the unit
of urb_packs is whatever data packet interval the device uses (possibly
less than one frame when using high speed devices).

Drop inbound packets that are smaller than expected. This has been
observed at the very beginning of the streaming transaction.

And when the hardware is in panic mode (which can only very rarely
happen in case of massive EMI chaos), mute the input channels.

Subject: sound: usb-audio: remove check_hw_params_convention()

This removes the check_hw_params_convention() function because
1) it is not necessary, as the hw_rule_* functions also work correctly
   (i.e., as no-ops) when the device supports all combinations of the
   audio format parameters; and
2) it would become too complex when adding a fourth altsetting-dependent
   hardware parameter, as this would require another three loops to
   check dependecies with rate/channels/format.

Subject: sound: usb-audio: save data packet interval in audioformat structure

The data packet interval needs to be available in the audioformat
structure, together with the other audio format parameters, so that it
can be used to influence ALSA hardware parameters.

Subject: sound: usb-audio: allow period sizes less than 1 ms

To enable periods shorter than 1 ms, we have to make sure that short
periods are only available for alternate settings that have a small
enough data packet interval.  Furthermore, the code that aligns URBs to
USB frames is now superfluous.

Subject: ALSA: us122l: Fix signedness in comparisions

Within 2.6.30's mergewindow, struct urb's transfer_buffer_length has become
unsigned. This changed an "int > int" comparision to an "unsigned > int" one
in snd_usb_122l.
Fix this by using a local int variable instead of urb->transfer_buffer_length
in comparisions.

Shorten playback_prep_freqn() a bit and tweak error-paths in
usb_stream_prepare_playback().

Subject: ALSA: us122l: add snd_us122l_free()

Use it to clean up snd_us122l_card_used[].

Without patch unplugging of an US122L soundcard didn't reset the
corresponding element of snd_us122l_card_used[] to 0.
The (SNDRV_CARDS + 1)th plugging in did not result in creating the soundcard
device anymore.
Index values supplied with the modprobe command line were not used correctly
anymore after the first unplugging of an US122L.

Reset the internal period position counter upon stream startup. This

applications such as pulseaudio.

Bumped the version number to 1.3.14.
