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 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

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.

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.

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.

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.

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

Regards.
