DarkIce: AlsaDspSource.cpp:265: Input/output error [0]

Input/output error usually means that Darkice doesn't receive anything from the sound card.

You have to run the appropriate Record_from... script first.

I've found that an extra

amixer -Dhw:0 cset name='AIF Playback Switch' on

can be needed too.

unfortunately, the same error occured. Is it necessary to use an external power supply:

sudo darkice -v9 -c /etc/darkice.cfg

You config file seems fine. I only changed the server name and  password and it streams just fine to my Icecast server.

An external power supply should only be necessary if you want to use the speaker amplifier on the card.

Which input is it you're trying to stream?

I'm trying to use the line-in.

Kind regardz, Wessel.

Hmm...

What is the output of these commands?

amixer -Dhw:0 cget name='AIF1TX1 Input 1' | tail -1

amixer -Dhw:0 cget name='AIF1TX2 Input 1' | tail -1

They should return "values=11" and "values=12"

Oeps, not good:

amixer -Dhw:0 cget name='AIF1TX1 Input 1' | tail -1

: values=0

amixer -Dhw:0 cget name='AIF1TX2 Input 1' | tail -1

: values=0

No, not good

values=0 means Input=none

That would indicate that the use case script Record_from_lineIn.sh has not been run.

Run that script and check again. If you get 11 and 12, try to stream.

These are the commands in the script:

amixer -Dhw:0 cset name='IN3L Volume' 8

amixer -Dhw:0 cset name='IN3R Volume' 8
amixer -Dhw:0 cset name='IN3 High Performance Switch' on

amixer -Dhw:0 cset name='IN3L Digital Volume' 128

amixer -Dhw:0 cset name='IN3R Digital Volume' 128

amixer -Dhw:0 cset name='AIF1TX1 Input 1' IN3L

amixer -Dhw:0 cset name='AIF1TX1 Input 1 Volume' 32

amixer -Dhw:0 cset name='AIF1TX2 Input 1' IN3R

amixer -Dhw:0 cset name='AIF1TX2 Input 1 Volume' 32

Thanks a lot Ragnar, that was the missing part!

Hello, I have this error message 
after setting up my hifiberry digi+ i/o board with darkice and a PI3:


Using config file: /etc/darkice.cfg
Using ALSA DSP input device: plughw:0,0
Using POSIX real-time scheduling, priority 4
Using aacplus codec
DarkIce: AlsaDspSource.cpp:265: Input/output error [0]

what does it mean?  How to solve the problem ?

I followed this configuration 
for the install of the hifiberry board:

sudo nano /boot/config.txt

dtoverlay = hifiberry-digi

# Enable audio (loads snd_bcm2835)
dtoverlay=hifiberry-digi

after restart, i have :

**** Liste des Périphériques Matériels PLAYBACK ****
carte 0: sndrpihifiberry [snd_rpi_hifiberry_digi], périphérique 0: HifiBerry Digi HiFi wm8804-spdif-0 []

Sous-périphérique #0: subdevice #0

sudo nano /etc/asound.conf

pcm.!default {
type hw card 0
}
ctl.!default {
type hw card 0
}


My config with darkice is :

reconnect = yes # reconnect to the server(s) if disconnected

irc = irc.yourserver.com
# IRC info related to the stream

Thanks for your answer
