I have installed the test image for the HifiBerry Digi.
The images does see the Digi but when I play a sound with aplay I get an error:
aplay: pcm_write:1710: write error: Input/output error.

When I run aplay -l he sees the HifiBerry digi.

Can someone help me with this?

Hi Jimmy,

this could be a problem with the data connection on the P5 header. Please check the soldering of the P5 connector on the Raspberry. Use a multimeter to check that there is a good connection between the P5 on the Raspberry and the Digi.

Best regards
Daniel

The problem isn't solved. The test image does work. But when I install RaspBian the modules are loaded and HifiBerry is found but can't play anything on the HifiBerry.

When I play music with mplayer I got this error:

This seems to be a problem with the mplayer installation that does not support MP3 decoding. Have anybody seen this before?

Looks like somebody had this problem before:
http://www.raspberrypi.org/phpBB3/viewtopic.php?t=7107&p=121986

Try, if this works:
mplayer -ao alsa:device=hw FILE

Solution seems to be to configure ALSA:
----------------
pcm.!default {
type hw
card 0
}

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

Also when i see into the Toslink output I doesn't see a red light. So my receiver can't get any input of the HifiBerry. And with the test image I see a red light all time.

Did you test it with the command line shown above?

I did test it with the command that you gave me.
But it didn't work.
I have installed the test image and i use that one now without any problems.
Tnx for the support.

Hey I got the same issue running check-systems.dac. Using the latest RaspBmc

All modules are loaded.

It hangs for a little while, then print:
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_digi], device 0: HifiBerry Digi HiFi wm8804-spdif-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
aplay: pcm_write:1710: write error: Input/output error

Looking in the other end of the TOSLINK cable, there's no red light.

It doesn't show up in xbmc settings either - just analoge and HDMI. Although, the very first time I started XBMC the option did appear.

I have verified that the soldering of P5 connector is well done using a multimeter.

Running "mplayer -ao alsa:device=hw FILE", I get this:

MPlayer svn r34540 (Debian), built with gcc-4.6 (C) 2000-2012 MPlayer Team

Hello Guys,

I face same issue - aplay: pcm_write:1947: write error: Input/output error. Please let me know if you've found solution for this.

Hi,

this usually means that there is already another process using the sound card.

Hi,

In my case, it was because of using wrong interrupt number for codec.

Regards,

Hi,

what exactly do you mean by "using wrong interrupt number"?

Best regards
