IntelHDA: jack output works, but no sound in laptop speakers

[Nyar]

Hello. I'm using ThinkPad T510 having Intel sound card with Parabola GNU/Linux (Arch Linux based distro).

$ uname -a

I've installed the latest version of OSS4 from the Arch AUR and had no troubles with that.

Code: Select all

$ cat /etc/rc.conf | grep DAEMONS=
DAEMONS=(syslog-ng !network wicd crond oss4 mpd dbus slim)


After system loading I see

Code: Select all

$ lsmod | grep oss
oss_usb               108983  4
oss_hdaudio           145640  10

It seems to work just fine in applications with OSS support (MPD for example), still only through headphones. I tried changing _all_ ossmix mixer settings, but haven't manage to make my internal speakers work. Awfully need your help in configuring. Could it be not a certain value but a _combination_ of values? Or maybe my sound card just isn't fully supported? I've only figured out that jack.black.mode1 affects my jack output. So here is my ossinfo and default ossmix values (with hdaudio_noskip=7 enabled in /usr/lib/oss/conf/oss_hdaudio.conf):

Hardly need your help in configuring. Could it be not a certain value but a _combination_ of values? Or maybe my sound card just isn't fully supported? I've only figured out that jack.black.mode1 affects my jack output. So here is my ossinfo and default ossmix values (with hdaudio_noskip=7 enabled in /usr/lib/oss/conf/oss_hdaudio.conf)

Hardly need your help in configuring.

Are you going to say that you do not need help?

with hdaudio_noskip=7 enabled in /usr/lib/oss/conf/oss_hdaudio.conf

Unconnected jacks are not supposed to work. You may better try the default.

Oh, very sorry for that! I meant «awfully», of course.

Unconnected jacks are not supposed to work. You may better try the default.

The thing is: I tried, but with no result. Is there any way to know what mixers should affect internal speakers?

What do you want of "generic driver"? It is as good as "vesa" and other GNU/PulseAudio crap.

Since oss_hdaudio is a "generic driver", it does not support "hardware mixing" and "jack-sensing" (except for ICH6). For the same reason, it may fail to work.

KNOWN PROBLEMS
In general Azalia based systems (laptops/motherboards) would require a custom driver to work properly. Due to enormous number of different systems it is not possible to develop such custom drivers for all systems. A generic driver is used for systems that don't have dedicated drivers.
Unfortunately the mixer and control panel interface (see ossmix ) for "generic" systems is very cryptic and difficult to understand. To solve problems with volumes or signal routing you need to start ossxmix and change the controls one at time until you get the desired effect.
http://manuals.opensound.com/usersguide ... audio.html

Try to fix the default. If it fails to work, you may try to write your own "custom driver" for your soundcard.

EDIT: Although "jack-sensing" is not likely to work with your soundcard, you may better disconnect your headphones, when you test internal speakers.

It seems that the internal speakers work with the default hdaudio_noskip=0 (in /usr/lib/oss/conf/oss_hdaudio.conf) on the same ThinkPad T510.
