Hello!
I have a strange problem. I installed volumio. I updated the firmware and
the OS.
I can see my hifiberry with aplay -l. But if I start "check-system.dac"
there is no sound and after a while aplay stops with
aplay: pcm_write:1710: write error: Input/output error
And now the STRANGE part.
On my denon receiver I see all the time "signal unlock"
Then I call mplayer with the following parameter
mplayer -ao alsa:device=hw=1,0 foobar.flac
and the sound start and plays perfectly, the
"signal unlock" disappears.
afterwards check-systems.dac plays the "beep"
and shows no error. The volumio software also
works without problems
so after each reboot I have to manually call
mplayer to get my Rasberry/Hifiberry in
a usable state.
Any ideas what could be the problem?
regards
Sven

HiFiBerry team Hi Sven,
can you post the output of "dmesg". I've had a similar problem before where a software tried to use 32kHz sample rate that does not work on the Digi.

Sven Sternberger Hi
This is the dmesg output after boot:
http://pastebin.com/FhCWh5ez
when I start check-system.dac
the following lines will be added:
> [ 383.955929] bcm2708-i2s bcm2708-i2s.0: I2S SYNC error!
> [ 404.073868] bcm2708-dmaengine bcm2708-dmaengine: DMA transfer could not be terminated
now I found in the mpd.conf
audio_output {
type "alsa"
name "Output"
device "hw:0,0"
dsd_usb "yes"
}
I replace "hw:0,0" with "hw:1,0", now my device works directly after boot :-).
The only strange thing is that aplay don't work before music is played with mplayer or mpd (with the new config) -
HiFiBerry team Hi Sven,
we have seen several issues with aplay. It sometimes seems to set incorrect samplerates or bit depths. It is possible that something like this happend here. Therefore I recommend using mplayer.
Best regards
Daniel
