sound: pcm_lib: fix unsorted list constraint handling

2009-09-09T03:33:23Z

commit b1ddaf681e362ed453182ddee1699d7487069a16 upstream. snd_interval_list() expected a sorted list but did not document this, so there are drivers that give it an unsorted list. To fix this, change the algorithm to work with any list. This fixes the "Slave PCM not usable" error with USB devices that have multiple alternate settings with sample rates in decreasing order, such as the Philips Askey VC010 WebCam. http://bugzilla.kernel.org/show_bug.cgi?id=14028 Reported-and-tested-by: Andrzej Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai Signed-off-by: Greg Kroah-Hartman

sound: seq_midi_event: fix decoding of (N)RPN events

2009-07-02T23:50:30Z

commit 6423f9ea8035138d70bae1a278d3b57b743f8b3e upstream. When decoding (N)RPN sequencer events into raw MIDI commands, the extra_decode_xrpn() function had accidentally swapped the MSB and LSB controller values of both the parameter number and the data value.

ALSA: Enable PCM hw_ptr_jiffies check only in xrun_debug mode

2009-05-27T09:04:30Z

The PCM hw_ptr jiffies check results sometimes in problems when a hardware doesn't give smooth hw_ptr updates. So far, au88x0 and some other drivers appear not working due to this strict check. However, this check is a nice debug tool, and the capability should be still kept. Hence, we disable this check now as default unless the user enables it by setting the xrun_debug mode to the specific stream via a proc file. Signed-off-by: Takashi Iwai

ALSA: Fix invalid jiffies check after pause

2009-05-27T09:04:18Z

The hw_ptr_jiffies has to be reset properly to avoid the invalid check of jiffies delta in snd_pcm_update_hw_ptr*() functions. Especailly this patch fixes the bogus jiffies check after the puase and resume. This patch is a modified version of the original patch by Jaroslav. Signed-off-by: Takashi Iwai

ALSA: pcm core - Avoid jiffies check for devices with BATCH flag

2009-04-28T13:10:16Z

The hardware devices with SNDRV_PCM_INFO_BATCH flag can't give the precise current position. And such hardwares have often big FIFO in addition to the ring buffer, and it screws up the jiffies check in pcm_lib.c. This patch adds a simple check of info flag so that the driver skips the jiffies check in snd_pcm_period_elapsed() when BATCH flag is set. Signed-off-by: Takashi Iwai

ALSA: add private_data to struct snd_jack

2009-04-14T14:15:09Z

Added private_data and private_free fields to struct snd_jack so that the caller can assign the data. It'll be helpful for avoiding the double-free of the jack instance. Signed-off-by: Takashi Iwai

[ALSA] pcm-midlevel: Add more strict buffer position checks based on jiffies

2009-04-10T10:28:58Z

Some drivers like Intel8x0 or Intel HDA are broken for some hardware variants. This patch adds more strict buffer position checks based on jiffies when internal hw_ptr is updated. Enable xrun_debug to see mangling of wrong positions. As a side effect, the hw_ptr interrupt update routine might do slightly better job when many interrupts are lost. Signed-off-by: Jaroslav Kysela
