Summary:                    No audio after recommended patch (see 0000216)
Description: 
This is a continuation of bug 0000216.  Would have added this comment there
but bug was closed.

Applied the patch
(http://galadriel.mat.utfsm.cl/~mjander/aureal/alsa/aureal-2.6.5.diff.gz)
cleanly, recompiled, rebooted twice.  Now I get no sound output at all. 
Checked with headphones, checked mixer levels.  

The modules (snd_au8830, snd_ac97_codec, snd_mpu401_uart, snd_rawmidi,
snd_seq_oss, snd_seq_midi_event, snd_seq, snd_seq_device, snd_pcm_oss,
snd_pcm, snd_page_alloc, snd_timer, snd_mixer_oss, snd) are loaded,
everything seems fine.  XMMS, Rhythmbox, etc. will "play" the files at a
normal rate using both ALSA and OSS outputs, but nothing comes out of the
card.

Let me know if there is any information that I can give you that will
help.

Hi,

- Why are you using patch 2.6.5 if you are using kernel 2.6.6 ?! Use the
patch for 2.6.6 instead:
http://galadriel.mat.utfsm.cl/~mjander/aureal/alsa/aureal-2.6.6.diff.gz
That wont change much, but its the latest.

- Please check your mixer settings *again*. Use alsamixer (or other ALSA
mixer), not a OSS mixer. Be sure to uncheck the "mute" toggles.
CDROM,line-in,video,auxiliar,etc audio won't be hearable through the
"headpones" output, since the codec is not capable to do so, and another
kind of workaround is needed for that.

- If you experience too low output level, toggle the "Externel Amplifier
Disable" control in alsamixer to set it right.

- Turn on your loudspeaker, take out your earplugs ... :D

- Any bad things reported on dmesg ?

You should not have any problem, many people are using the current driver
without problem, i use them everyday (what else could i say ?) ...

Best Regards

Manuel Jander
