  Hi 

I rework my last patch for audio and now audio works well. This patch can be submited to GIT tree
Quality of audio now is good for SECAM-DK. For other standard I set some value from datasheet need some tests.

1. Fix pcm buffer overflow
2. Rework pcm buffer fill method
3. Swap bytes in audio stream
4. Change some registers value for TM6010
5. Change pcm buffer size

With my best regards, Dmitry.

This didn't seem to work for PAL-M. Probably, the right value for it is 0x22, to
follow NTSC/M, since both uses the same audio standard.

On some tests, I was able to receive some audio there, at the proper rate, with a
tm6010-based device. It died when I tried to change the channel, so I didn't rear
yet the real audio, but I suspect it will work on my next tests.

Yet, is being hard to test, as the driver has a some spinlock logic broken.
I'm enclosing the logs.

I was able to test only when using a monitor on the same machine. All trials of
using vnc and X11 export ended by not receiving any audio and hanging the machine.

I suspect that we need to fix the spinlock issue, in order to better test it.

Cheers,
Mauro.

Well, any of us ;)

I did a BKL lock fix series of patches, and hverkuil is improving them.
They'll make easier to avoid problems inside tm6000. We just need to make
sure that we'll hold/release the proper locks at tm6000-alsa, after applying
it at the mainstream.

Cheers,
Mauro

Yes. I have some as crash from mplayer and arecord.
