* sound: usb-audio: make the MotU Fastlane work againClemens Ladisch2009-05-27
| | | | | | | | | | | | | Kernel 2.6.18 broke the MotU Fastlane, which uses duplicate endpoint numbers in a manner that is not only illegal but also confuses the kernel's endpoint descriptor caching mechanism. To work around this, we have to add a separate usb_set_interface() call to guide the USB core to the correct descriptors.

| | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <fzu@wemgehoertderstaat.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* sound: usb-audio: allow period sizes less than 1 msClemens Ladisch2009-04-06
| | | | | | | | | | 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.

| | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
