Hi, thanks for your effort,
I've tried that patch and with a little correction it works as expected - no
more click noise.
It's necessary to move the line
.reboot_notify = conexant_reboot_notify,
from
static const struct hda_codec_ops conexant_patch_ops = {
to
static const struct hda_codec_ops cx_auto_patch_ops = {
when rebooting "auto model detection".
One thing about
snd_hda_codec_set_power_to_all(codec, codec->afg, AC_PWRST_D3, false);
I think it's not necessary to turning every single pin to D3, just pin for the
Speaker, like this
snd_hda_codec_write(codec, 0x10, 0, AC_VERB_SET_POWER_STATE, AC_PWRST_D3);
or
snd_hda_codec_write(codec, codec->start_nid, 0, AC_VERB_SET_POWER_STATE,
AC_PWRST_D3);
but it's up to you because it works :)
The rest regressions when using "auto model detection":
1) There is a wrong AC_VERB_SET_CONNECT_SEL setting. Speaker 0x10 and
Headphones 0x11 (and maybe dock station 0x12) are connected to Audio Output
0x19 instead of Audio Mixer 0x17. Look at post #8.
2) I don't know how to explain it but there is a wrong PCM level. Sound output
is muted in the "0% <-> unamplified" part of the volume slider and is working
in the "unamplified <-> 100% ->" part only and it's annoying; according to the
code from patch_conexant.c (old model setting)
switch (codec->subsystem_id >> 16) {
case 0x103c:
case 0x1631:
case 0x1734:
case 0x17aa:
/* HP, Packard Bell, Fujitsu-Siemens & Lenovo laptops have
* really bad sound over 0dB on NID 0x17. Fix max PCM level to
* 0 dB (originally it has 0x2b steps with 0dB offset 0x14)
*/
snd_hda_override_amp_caps(codec, 0x17, HDA_INPUT,
(0x14 << AC_AMPCAP_OFFSET_SHIFT) |
(0x14 << AC_AMPCAP_NUM_STEPS_SHIFT) |
(0x05 << AC_AMPCAP_STEP_SIZE_SHIFT) |
(1 << AC_AMPCAP_MUTE_SHIFT));
break;
}
the driver doesn't allow amplified part because sound is distorted over 0dB of
the PCM level so there is no need amplified part of the volume slider.

Title:
[Thinkpad R61i/T61] Lenovo sound chip Conexant CX20549 Venice doesn't
work correctly.
Status in “alsa-driver” package in Ubuntu:
Incomplete
Bug description:
Computer: IBM Lenovo Thinkpad R61i
Card: HDA Intel
Sound chip: Conexant CX20549 (Venice)
Device: 00:1b.0 Audio device [0403]: Intel Corporation 82801H (ICH8 Family)
HD Audio Controller [8086:284b] (rev 03)
Subsystem: Lenovo ThinkPad T61 [17aa:20ac]
System: Ubuntu Oneiric 11.10 (desktop-i386)
Kernel: 3.0.0-12-generic-pae#20-Ubuntu SMP Fri Oct 7 16:37:17 UTC 2011
Problems:
1) Integrated microphone doesn't work at all because the driver uses node
0x14 instead of 0x15 for integrated mic and node 0x12 instead of 0x14 for
external mic.
2) Sound output is muted in the "0% <-> unamplified" part of the volume
slider and is working in the "unamplified <-> 100% ->" part only; the driver
doesn't allow amplified part because sound is distorted over 0dB of the PCM
level so there is no need amplified part of the volume slider.
Solution: Attached patch is fixing nodes of integrated and external
microphone and is removing the amplified part of the volume slider.
