Hi,

I'm struggling with mic+headphone issues in Samsung R540. I posted below
message to alsa-user, but couldn't get any response. I'll be really
appreciated for any help. BTW, I can provide any other information to
fix the problem. (Even remote access maybe.) I'm really in need to solve
this issue.


Regards.

Hello,

Looks like your Capture switch is disabled. Run alsamixer, find Capture 
(press F4) and then press Space to start capturing sound. Obviously, you 
will need to run arecord after that (I recommend using -vv to see the 
bar moving as you speak anything into mic).

P.S. You shouldn't send messages to alsa-devel-request email, it is 
intended for list management functions.

Ok, this is not the first time I feel like a dumb. Thanks for the prompt
reply, it fixed the mic problem.

Can you say anything about the headphone problem? Plugging -in/-out
headphones doesn't have any effect.

It's not easy to say anything definite without having similar laptop at 
hands, but at the first glance it looks like the model you've selected 
for your soundcard (model=basic) attaches headphones to the wrong pin 
complex (Node 0x15 in the output [1]). Node 0x21 seems to be correct one 
for me, but it is just a guess which you can check by downloading HDA 
Analyzer GUI tool (python and pygtk are required) from ALSA website [2] 
and unmuting Node 0x21 output amplifiers manually, without using 
alsamixer or any other ALSA tool. This wouldn't help to fix your problem 
once and forever, but may help to see if the guess is correct. If it is, 
try another model for your soundcard (my impression is that 
autodetection, i.e. removing model= part altogether usually gives good 
results - you can even try to do it in a first place, without resorting 
to HDA Analyzer, and see if that helps). If it's not, try to loop 
through other pin widgets (0x1a is another suspect) in HDA Analyzer and 
unmute them while trying to play something in your headphones.

if the headphone is at 0x21 instead of 0x15 , you will need create a
alc269_r590_mixer which has HP playback switch at 0x21 , remove the mono
playback switch by using the alc269_base_mixer for your new model
alc269_r590

Node 0x21 [Pin Complex] wcaps 0x40018d: Stereo Amp-Out
  Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1
  Amp-Out vals:  [0x80 0x80]
  Pincap 0x0000001c: OUT HP Detect
  Pin Default 0x0121101f: [Jack] HP Out at Ext Rear
    Conn = 1/8, Color = Black
    DefAssociation = 0x1, Sequence = 0xf
  Pin-ctls: 0x00:
  Unsolicited: tag=00, enabled=0
  Connection: 2
     0x0c* 0x0d


Node 0x15 [Vendor Defined Widget] wcaps 0xf00000: Mono
  Control: name="Headphone Playback Switch", index=0, device=0
    ControlAmp: chs=3, dir=Out, idx=0, ofs=0
Node 0x16 [Vendor Defined Widget] wcaps 0xf00000: Mono

Hi,

Thanks Raymond and Valentine for your detailed replies. I played with
HDA Analyzer GUI but couldn't manage to make headphones work, I am
probably missing something again. Would you mind elaborating the details
about the steps that I need to follow? For instance, Raymond, with all
my respect, I really don't have an idea about how to do what you want me
to do. (E.g., "create a alc269_r590_mixer which has HP playback switch
at 0x21, remove the mono playback switch by using the alc269_base_mixer
for your new model alc269_r590") A last push would be really helpful.


Regards.

If I were you, I'd do the following:
1. Reload soundcard driver with no model specified (i.e. delete 
"model=basic" from modprobe.conf and reboot or do rmmod 
snd-hda-intel/modprobe snd-hda-intel model=auto). This will reset all 
mixers, so you'll need to enable Capture again in order for mic to work.
2. If headphones work, you are done.
3. If not, run HDA Analyzer, find "PIN 0x21" in the left sidebar. Look 
at "Output Amplifier" checkbox group and clear mute checkboxes. Then, 
switch to "AUD_MIX (0x0C)" in the same sidebar and adjust output volume 
(the same checkbox group). You should hear sound in your headphones.
4. If not, look at PIN 0x1a and do the same as at step 3.
5. If this doesn't help, file a bug report.

Regards,
Valentine

Despite I tried this setting at least 4 times, this time it worked in
the first try. Maybe I should quit PhD while I am the start of it.

Thanks so much Raymond and Valentine for your helpful support. I am in
dept to you.

Not necessarily. At least, having a doctorate degree entitles you to a 
bit of absent-mindness ;)

Welcome. Next time I'll be in Turkey you can buy me a beer. Just kidding :)

Good luck in your studies!
