Emvy24control s/pidf input issue

[Udo van den Heuvel]

Hello,

I just noticed that S/PDIF input on my Audiophile 2496 does not work.
I see:

[udo@wda ~]$ envy24control
using    --- input_channels: 0
         --- output_channels: 4
         --- pcm_output_channels: 8
         --- spdif in/out channels: 2
Unable to read S/PDIF input switch: No such file or directory

Changing the Digital Input from coax to optical or vice versa
gives:
Unable to write S/PDIF on/off switch: No such file or directory
Unable to write S/PDIF input switch: No such file or directory

This is on Fedora 8 x86_64 with alsa-tools 1.0.12-4 from Fedora Core 7,
envycontrol 0.6.0.
S/PDIF output works without a problem. Did not have S/PDIF input working
before, as far as I remember.

Using -v I do not see signal in the meters.

In the source I see in spdif_input_update:

        if ((card_eeprom.subvendor != ICE1712_SUBDEVICE_DELTADIO2496) &&
            ! card_is_dmx6fire)
                return;
        if ((err = snd_ctl_elem_read(ctl, spdif_input)) < 0)
                g_print("Unable to read S/PDIF input switch: %s\n",
snd_strerror(err));
(etc)

Why does snd_ctl_elem_read fail?
How could I make S/PDIF input work again?

Tips are very welcome!

Kind regards,
Udo

1.0.12 looks very old.  Try 1.0.16 or later one and let us know if the
problem still exists.

I still get the message now, but using envy24control 0.6.0 from
alsa-tools 1.0.16 I do get meters.

Any ideas about the messages I see?

You can ignore 'Unable to read S/PDIF input switch' messages.  It's an
unimplemented (non-existing) feature for Audiophile 2496.

Ah, OK.
Thanks for the quick reply.
With some asound.conf magic I appear to get some audio into the machine now.
I wil lcheck this out!
