   Hi, I am running Slitaz-5-rc3 3.2.71-slitaz.

   lspci shows me that I have a

   Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 03)
   00:1f.6 Mode

   Alsamixer has all settings on nothing is muted. However, when I play a test wav file using aplay nothing is heard although aplay does not report any problems.

   lsmod shows that the drivers are loaded.

   snd_intel8x0m 8027 0
   snd_intel8x0 19880 1
   snd_ac97_codec 76877 2 snd_intel8x0m,snd_intel8x0
   ac97_bus 698 1 snd_ac97_codec
   snd_pcm 42938 3 snd_intel8x0m,snd_intel8x0,snd_ac97_codec
   snd_page_alloc 4669 3 snd_intel8x0m,snd_intel8x0,snd_pcm
   snd_timer 12069 1 snd_pcm
   snd 33686 7 snd_intel8x0m,snd_intel8x0,snd_ac97_codec,snd_pcm,snd_timer
   soundcore 3254 1 snd

   One thing I noticed is that the function key Fn+Esc which is supposed to mute/unmute sound on this Toshiba Portege R200 does not function. xev program does not record any keystrokes when Fn+Esc is pressed. However, if keyboard has muted the sound card one would think that it would appear in the sound applet which shows that it is in unmuted state.

   Any ideas or suggestions will be appreciated.

   Thanks

   Not sure the importance of this but I noticed that when run aplay the file gets played at a sampling rate of 88200 although it has a sampling rate of 44100.

   Finally had a breakthrough....

   In alsamixer there was a control called 'Head Phone Jack Sense' - just muted it and now I can playback sounds without any issue. A bit strange but hey, it works!

   Thanks for reporting your resolution.
   Head Phone Jack Sense should only disable laptop speakers and/or speaker output port when a 3.5mm headphone jack is plugged into the laptops headphone port.
   Documented bug:
   http://www.thinkwiki.org/wiki/AD1981B
   Linux ALSA driver
   Note
   On some models (T40, T43p, ... R51e ...) audio is muted if either Headphone or Line Jack are unmuted. See also ALSA Wiki FAQ [1]. Also, if Headphone Sense or Line Jack Sense are unmuted audio is dead (R50e, R52, X40). By default the Sense settings are not shown in mixer.

   @mojo, thanks for the additional info.

   For the benefit of others who may stumble across this issue, the laptop in question is a Toshiba Portege R100. Note that both Headphone Jack Sense and Line Jack Sense had to be muted to get audio working.
