sound: usb-audio: add workaround for Blue Microphones devices

2009-07-30T21:39:03Z

commit 8886f33f25083a47d5fa24ad7b57bb708c5c5403 upstream. Blue Microphones USB devices have an alternate setting that sends two channels of data to the computer. Unfortunately, the descriptors of that altsetting have a wrong channel setting, which means that any recorded data from such a device has twice the sample rate from what would be expected. This patch adds a workaround to ignore that altsetting. Since these devices have only one actual channel, no data is lost.

sound: usb-audio: make the MotU Fastlane work again

2009-05-27T09:25:33Z

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. Signed-off-by: Daniel Mack Signed-off-by: Takashi Iwai

ALSA: us122l: add snd_us122l_free()

2009-04-20T11:39:38Z

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.

ALSA: us122l: Fix signedness in comparisions

2009-04-17T13:24:07Z

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().
