[ALSA] hda-intel - Don't try to probe invalid codecs

Fix the max number of codecs detected by HD-intel (and compatible)
controllers to 3.  Some hardware reports extra bits as if
connected, and the driver gets confused to probe unexisting codecs.

usbaudio - Fix Oops with unconventional sample rates

2007-03-09T18:50:19+00:00

The patch fixes the memory corruption by the support of unconventional
sample rates.  Also, it avoids the too restrictive constraints if
any of usb descriptions contain continuous rates.

usbaudio - Fix Oops with broken usb descriptors

2007-03-09T18:50:19+00:00

This is a patch for ALSA Bug #2724. Some webcams provide bogus
settings with no valid rates. With this patch those are skipped.

[PATCH] ALSA: Fix sysfs breakage

2007-01-29T22:32:53+00:00

The recent change for a new sysfs tree with card* object breaks the
/sys/class/sound tree if CONFIG_SYSFS_DEPRECATED is enabled.
The device in each entry doesn't point the correct device object:

  /sys/class/sound
  ...
  |-- pcmC0D0c
  |   |-- dev
  |   |-- device -> ../../../class/sound/card0
  |   |-- pcm_class
  |   |-- power
  |   |   `-- wakeup
  |   |-- subsystem -> ../../../class/sound
  |   `-- uevent

Also, this change breaks some drivers (like sound/arm/*) referring
card->dev directly to obtain the device object for memory handling.

This patch reverts the semantics of card->dev to the former version,
which points to a real device object.  The card* object is stored in a
new card->card_dev field, instead.  The device parent is chosen either
card->dev or card->card_dev according to CONFIG_SYSFS_DEPRECATED to
keep the tree compatibility.
Also, card* isn't created if CONFIG_SYSFS_DEPRECATED is enabled.  The
reason of card* object is a root of all beloing devices, and it makes
little sense if each sound device points to the real device object
directly.

[ALSA] Repair snd-usb-usx2y over OHCI

2007-01-23T08:23:36+00:00

The previous patch 'Repair snd-usb-usx2y for usb 2.6.18' assumed
urb->start_frame roll over beyond MAX_INT for both UHCI & OHCI.
This isn't true until now (kernel 2.6.20).
Fix this by only looking at the common between OHCI & UHCI Frame number
range.
This is for mainline and stable kernels >= 2.6.18.

[ALSA] usbaudio - Fix kobject_add() error at reconnection

2007-01-09T08:14:15+00:00

Fixed the error from kobject_add() at reconnection the usb audio device.
This happens when an app keeps opening a device while the device is
replugged, due to the confliction of the internal bookkept index and
the really empty slot.

[ALSA] _snd_cmipci_uswitch_put doesn't set zero flags

2007-01-09T08:06:18+00:00

Playing with spdif output on cmipci i've noticed the SPDO5V option does
not change appropriate bits the register.
The _snd_cmipci_uswitch_put checks the change in flags in wrong way.
If 'active' state of an option corresponds to a _zero_ bits in a hw
register then function fails. The SPDO5V is the sample.
In the most cases 'active' state of option is set through an non-zerio
bits in a register. This case works fine.
The fix attached.
Unfortunately i was unable to change spdif output voltage anyway.
Although the register changes right at least.
