[alsa-devel] Emvy24control s/pidf input issue
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!
