ALSA: hda - Fix the dock headphone output on Fujitsu Lifebook E780

2015-08-03T16:29:41+00:00

commit 4df3fd1700abbb53bd874143dfd1f9ac9e7cbf4b upstream.

Fujitsu Lifebook E780 sets the sequence number 0x0f to only only of
the two headphones, thus the driver tries to assign another as the
line-out, and this results in the inconsistent mapping between the
created jack ctl and the actual I/O.  Due to this, PulseAudio doesn't
handle it properly and gets the silent output.

The fix is to ignore the non-HP sequencer checks.

ALSA: hda - Add headset support to Acer Aspire V5

2015-08-03T16:29:41+00:00

commit 7819717b11346b8a5420b223b46600e394049c66 upstream.

Acer Aspire V5 with ALC282 codec needs the similar quirk like Dell
laptops to support the headset mic.  The headset mic pin is 0x19 and
it's not exposed by BIOS, thus we need to fix the pincfg as well.

commit 88776f366ede7d9cdce60bd2c9753dd6d6fa8b77 upstream.

Fujitsu Lifebook E752 laptop needs a similar quirk done for Lifebook
T731.  Otherwise the headphone is always muted.

ALSA: hda - Fix mute-LED fixed mode

2015-05-13T12:15:41+00:00

commit ee52e56e7b12834476cd0031c5986254ba1b6317 upstream.

The mute-LED mode control has the fixed on/off states that are
supposed to remain on/off regardless of the master switch.  However,
this doesn't work actually because the vmaster hook is called in the
vmaster code itself.

This patch fixes it by calling the hook indirectly after checking the
mute LED mode.

ALSA: emu10k1: Emu10k2 32 bit DMA mode

2015-05-13T12:15:41+00:00

commit 7241ea558c6715501e777396b5fc312c372e11d9 upstream.

Looks like audigy emu10k2 (probably emu10k1 - sb live too) support two
modes for DMA. Second mode is useful for 64 bit os with more then 2 GB
of ram (fixes problems with big soundfont loading)

1) 32MB from 2 GB address space using 8192 pages (used now as default)
2) 16MB from 4 GB address space using 4096 pages

Mode is set using HCFG_EXPANDED_MEM flag in HCFG register.
Also format of emu10k2 page table is then different.

ALSA: emu10k1: Fix card shortname string buffer overflow

2015-05-13T12:15:41+00:00

commit d02260824e2cad626fb2a9d62e27006d34b6dedc upstream.

Some models provide too long string for the shortname that has 32bytes
including the terminator, and it results in a non-terminated string
exposed to the user-space.  This isn't too critical, though, as the
string is stopped at the succeeding longname string.

This patch fixes such entries by dropping "SB" prefix (it's enough to
fit within 32 bytes, so far).  Meanwhile, it also changes strcpy()
with strlcpy() to make sure that this kind of problem won't happen in
future, too.

ALSA: emu10k1: don't deadlock in proc-functions

2015-05-06T19:56:23+00:00

commit 91bf0c2dcb935a87e5c0795f5047456b965fd143 upstream.

The functions snd_emu10k1_proc_spdif_read and snd_emu1010_fpga_read
acquire the emu_lock before accessing the FPGA. The function used
to access the FPGA (snd_emu1010_fpga_read) also tries to take
the emu_lock which causes a deadlock.
Remove the outer locking in the proc-functions (guarding only the
already safe fpga read) to prevent this deadlock.

[removed superfluous flags variables too -- tiwai]

ALSA: hda - Fix headphone pin config for Lifebook T731

2015-04-19T08:10:46+00:00

commit cc7016ab1a22fb26f388c2fb2b692b89897cbc3e upstream.

Some BIOS version of Fujitsu Lifebook T731 seems to set up the
headphone pin (0x21) without the assoc number 0x0f while it's set only
to the output on the docking port (0x1a).  With the recent commit
[03ad6a8c93b6: ALSA: hda - Fix "PCM" name being used on one DAC when
 there are two DACs], this resulted in the weird mixer element
mapping where the headphone on the laptop is assigned as a shared
volume with the speaker and the docking port is assigned as an
individual headphone.

This patch improves the situation by correcting the headphone pin
config to the more appropriate value.
