How to fix "Invalid type for PCM iec958:"?

How to fix "Invalid type for PCM iec958:"?

[Philip A. Prindeville]

I've been seeing:

alsa-init: 1 soundcard found, using: iec958:{CARD 0 AES0 0x02 AES1 0x82 
AES2 0x00 AES3 0x02}
ALSA lib pcm.c:1851:(snd_pcm_open_conf) Invalid type for PCM 
iec958:{CARD 0 AES0 0x02 AES1 0x82 AES2 0x00 AES3 0x02} definition (id: 
iec958, value: cards.pcm.iec958)
alsa-init: playback open error: Invalid argument


And went looking via Google if this is anything obvious.  I saw several
other postings about having the same issue, but no clear replies about
what causes it, or how to fix it.

Should this be a FAQ question?  BTW:  What *is* the fix?

Thanks,

-Philip

This depends on the hardware and driver you use.
Most likely, the SPDIF I/O is not supported or defined in the system
configuration.

It's configured for devices/drivers known to work, but not all
existing ones in the world.

Check your hardware and see alsa-lib/src/conf/cards/*.conf (installed
to /usr/share/alsa/cards).

Ok, does anyone have a config file for a VIA8237?  And how does
the "private_string" get set and interpolated into:

                files [
                        {
                                @func concat
                                strings [
                                        { @func datadir }
                                        "/cards/"
                                        { @func private_string }
                                        ".conf"
                                ]
                        }
                ]

It's already in alsa-lib 1.0.9.
