I hope you do not mind that I have contacted you directly.

I would like to ask whether anyone has developed a driver for cs4281 working in
a dual codec sound card.

We have developed such a card, and it works fine with a single cs4299 codec,
but current alsa-driver-0.9.0rc1 fails with:

ALSA ../alsa-kernel/pci/cs4281.c:1455: DLLRDY not seen
CS4281 soundcard not found or device busy

when we connect another codec configured as slave (no quartz signal on
secondary, but SYNC, BIT_CLK, SDATA_OUT, SDATA_IN, RESET connected).

I have tried to increase the timeout to 1 s, but without any result.

Any advice?

Is the programming manual cs4281tm.pdf available at
http://www.alsa-project.org/alsa/ftp/manuals/cirrus/cs4281tm.pdf the most
recent one?

Best regards,
