RE: [PATCH] cs46xx SPDIF input && some cleanups && bug fixes

[Friedrich.Ewaldt]

Hi,

SPDIF input works with my Terratec DMX XFire thanks to Benny's newest patch.
(@Benny: Thanks for remailing the attachment)
I've got only one minor problem:
Switching around in alsamixer at the SPDIF controls for some time causes a
high frequency tone to be played back all the time until I reboot. I'll have
to do further examinations when this happens exactly.
regards, fritz_e

It's a known problem, read the note in cs46xx_lib.c, i think it's becourse
some times the DSP tasks get unsynchronized. I dont know how to fix it yet.

To get around the problem just mute and unmute the SPDIF input controll
in mixer and,  that usually fix it.

Now I understand what you was refering to, as finally it has happen to 
me to -;) (... no reason to be happy)
This is yet another problem.

If you umute/mute the SPDIF input while you are playbacking something 
the hole DSP seems to hang, sending
a high frequency tone, probably course some garbage left in the HW FIFO.
So, just dont do that for the moment. Reloading the driver, (or 
rebooting if you want) helps when it happens.

Hopefully I've got a fix for this problem soon.
