Description Jason Enochs 2007-06-30 18:40:35 EDT
Description of problem:  
I have a new laptop and just installed FC7 and I have no sound.  I have tried
several suggestions to fix the problem.  I am NOT a Linux guru.  I have run
alsamixer and channels are not muted.  I added the option "model=3stack" but
that also did nothing.  I have installed the latest alsa drivers.  I have even
sacrificed a chicken to TUX the Linux God.  He was not impressed.

 Probably means nothing but when I tried to play a test sound using "aplay -D
hw:0 /usr/share/sounds/phone.wav --- I got the following warning:

[root@localhost ~]# aplay -D hw:0 /usr/share/sounds/phone.wav
Playing WAVE '/usr/share/sounds/phone.wav' : Signed 16 bit Little Endian, Rate
44100 Hz, Stereo
Warning: rate is not accurate (requested = 44100Hz, got = 48000Hz)
         please, try the plug plugin

 Ok, after many hours online I think that it may be possible that I have a DSDT
problem. I found instructions on how to fix a DSDT at this link:


Unfortunately, obtaining my computer science degree did not involve much Linux.
Simple steps like..... 6. Recompile your kernel    involve many more steps like
google "how to recompile a Linux kernel"....   Yes, I am an idiot.  I have been
in  Linux-land for only a few days now.  I just want sound without booting into
the Windows side of my box.  UUUGGG....I seem to be getting some sick
satisfaction from this quest!!??......but not much sleep.
Comment 5 Jason Enochs 2007-07-02 22:22:38 EDT
 OK, it appears that the only fix for some (not all) Toshiba users that employ
the Conexant codec is to either:

 1. Custom build your DSDT.  (not for beginners)
 2. Add "acpi=off irqpol" to your boot command line and give up some of your
power management functions.

    I selected option #2 and now I have perfect sound and no battery life
indicator in my toolbar.  I can live with that until a better fix is worked out.
