ALSA: snd-usb-caiaq: fix reported elapsed periods -
Reset the internal period position counter upon stream startup. This
fixes initial aplay underruns and problems related to latency picky
applications such as pulseaudio.Bumped the version number to 1.3.14.

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.Signed-off-by: Karsten Wiese

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().Signed-off-by: Karsten Wiese

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.Signed-off-by: Clemens Ladisch

The data packet interval needs to be available in the audioformat
structure, together with the other audio format parameters, so that it

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.Signed-off-by: Clemens Ladisch
Signed-off-by: Takashi Iwai -
When listing the device's sample formats in the stream? proc file, the
sample format number itself is rather obscure, so we better show the

When checking for the maximum queue length, we have to take into account

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.

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.Signed-off-by: Clemens Ladisch

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.Signed-off-by: Clemens Ladisch
