*** Some errors were detected during the tests ***
But when using cdcontrol navigating the audiocd is possible, but sound output is just missing

Code: 
# mixer
Mixer vol      is currently set to  80:80
Mixer pcm      is currently set to 100:100
Mixer line     is currently set to 100:100
Mixer mic      is currently set to   0:0
Mixer mix      is currently set to   0:0
Mixer rec      is currently set to   0:0
Mixer ogain    is currently set to  77:77
Recording source: mic

A mixer for "cd" is missing. This might be the reason I get no sound from audiocd?
Have read a lot of manuals and posts, but still have no cue how to solve this.
 
mixer(8)

The mixer utility is used to set and display soundcard mixer device levels. It may also be used to start and stop recording from the soundcard.
The list of mixer devices that may be modified are:

vol, bass, treble, synth, pcm, speaker, line, mic, cd, mix, pcm2,
rec, igain, ogain, line1, line2, line3, dig1, dig2, dig3, phin,
phout, video, radio, and monitor.

Not all mixer devices are available.

Code: 
# mixer cd
mixer: unknown device: cd
usage: mixer [-f device] [-s | -S] [dev [+|-][voll[:[+|-]volr]] ...
       mixer [-f device] [-s | -S] recsrc ...
       mixer [-f device] [-s | -S] {^|+|-|=}rec rdev ...
 devices: vol, pcm, line, mic, mix, rec, ogain
 rec devices: line, mic, mix

What can be done to add cd as a device of mixer?
 
it gets worse ..

after reinstalling oss dmesg ends like this
Code: 
.
Starting sshd.
Starting cron.
mixer:
SOUND_MIXER_READ_DEVMASK
:
Device not configured
Starting background file system checks in 60 seconds.
please help me as I'm developing acute Durett-syndrome.
 
Looks like answers get rare here. :(

Perhaps this question can be answered by someone:

Can an audiocd be played on a FreeBSD-8.0 with snd_hda driver without xorg etc. just using cdcontrol? Is it necessary that mixer shows the device "cd" in order to hear sound from cdrom or not?

RTFM SND_HDA (4) talks about extensive verbose messages to diagnose but stays short of explaining how to get them.

I'm still not sure at all if it is necessary to add device.hints in order to solve this. Am I on the right path at all?
 
Not all devices support all mixer options. Perhaps your HDA soundcard simply doesn't support an audiocd line. I have two HDA machines that are like that.

You'll probably want to use an audio player that uses digital extraction to play CD tracks. I know xmms used to be able to do this, but I'm not sure about any others.

EDIT: BTW, you seem to be mixing both the snd_hda (native FreeBSD driver) and oss_hdaudio (OSSv4 driver) drivers. If neither driver shows a CD mixer control (check the OSSv4 driver controls with ossmix or ossxmix) then your hardware is almost certainly missing that mixer.

To get verbose messages on your system, select the right option from the boot menu.
