ALSA: usb - disable broken hw volume for Tenx TP6911

2012-10-12T20:28:10+00:00

commit c10514394ef9e8de93a4ad8c8904d71dcd82c122 upstream.

While going through Ubuntu bugs, I discovered this patch being
posted and a confirmation that the patch works as expected.

Finding out how the hw volume really works would be preferrable
to just disabling the broken one, but this would be better than
nothing.

ALSA: snd-usb: fix clock source validity index

2012-08-09T15:27:53+00:00

commit aff252a848ce21b431ba822de3dab9c4c94571cb upstream.

uac_clock_source_is_valid() uses the control selector value to access
the bmControls bitmap of the clock source unit. This is wrong, as
control selector values start from 1, while the bitmap uses all
available bits.

In other words, "Clock Validity Control" is stored in D3..2, not D5..4
of the clock selector unit's bmControls.

ALSA: usb-audio: fix rate_list memory leak

2012-06-09T15:33:01+00:00

commit 5cd5d7c44990658df6ab49f6253c39617c53b03d upstream.

The array of sample rates is reallocated every time when opening
the PCM device, but was freed only once when unplugging the device.

ALSA: usb-audio - Fix the missing volume quirks at delayed init

2011-11-21T22:31:17+00:00

commit dcaaf9f2c16b56f8bb316881fcd3f15c18fc71e7 upstream.

In the recent usb-audio driver, the initialization of volume ranges
may be delayed when the device doesn't respond well at the probing time.
But the volume quirks for certain devices are applied only in
mixer_ctl_feature_info() thus only at the very first probe and will be
missing when the volume range is initialized later.

This patch moves the volume quirk code to be always called from the
volume-range extraction (get_min_max()), so that the quirks are properly
applied in the later init time.

ALSA: usb-audio - Check the dB-range validity in the later read, too

2011-11-21T22:31:17+00:00

commit 9fcd0ab130579d9742538340edda3225f2b49a3e upstream.

When the initial check of dB-range failed due to the read error, try to
check again at the later read, too.  When an invalid dB range is found,
remove TLV flags and notify the mixer info change.

ALSA: ua101: fix crash when unplugging

2011-11-11T17:36:50+00:00

commit 862a6244eb9f9f5123fe819454fcfcae0ee1f2f9 upstream.

If the device is unplugged while running, it is possible for a PCM
device to be closed after the disconnect callback has returned.  This
means that kill_stream_urb() and disable_iso_interface() would try to
access already-invalid or freed USB data structures.

The function free_usb_related_resources() was intended to prevent this,
but forgot to clear the affected variables.

ALSA: usb-audio: Check for possible chip NULL pointer before clearing probing flag

commit 61a6a108d15213f5ee06332e1e7766d3860e4453 upstream.

Before clearing the probing flag in the error exit path, check that the
chip pointer is not NULL.

ALSA: usb-audio - clear chip->probing on error exit

2011-10-03T18:41:02+00:00

commit 362e4e49abe53e89d87455dfcd7c1bbaf08a839d upstream.

The Terratec Aureon 5.1 USB sound card support is broken since kernel
2.6.39.
2.6.39 introduced power management support for USB sound cards that added
a probing flag in struct snd_usb_audio.

During the probe of the card it gives following error message :

usb 7-2: new full speed USB device number 2 using uhci_hcd
cannot find UAC_HEADER
snd-usb-audio: probe of 7-2:1.3 failed with error -5
input: USB Audio as
/devices/pci0000:00/0000:00:1d.1/usb7/7-2/7-2:1.3/input/input6
generic-usb 0003:0CCD:0028.0001: input: USB HID v1.00 Device [USB Audio]
on usb-0000:00:1d.1-2/input3

I can not comment about that "cannot find UAC_HEADER" error, but until
2.6.38 the card worked anyway.
With 2.6.39 chip->probing remains 1 on error exit, and any later ioctl
stops in snd_usb_autoresume with -ENODEV.
