I just noticed that S/PDIF input on my Audiophile 2496 does not work.
[udo at 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
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,
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) &&
if ((err = snd_ctl_elem_read(ctl, spdif_input)) < 0)
g_print("Unable to read S/PDIF input switch: %s\n",
Why does snd_ctl_elem_read fail?
How could I make S/PDIF input work again?
Tips are very welcome!
