Yes, an rpi-update will install a new kernel from the Foundation, without drivers for the Wolfson card.

frangip I see the those lines from your syslog in mine too, on my working system.

I think they are some of the harmless "trace errors" that are mentioned in the installation manual.

HI Ragnar

I Downloaded the img you propoused in this link http://www.element14.com/community/thread/32321?start=0&tstart=0,

And when i try to execute use_case script, i'm having the same error, amixer: Cannot find the given element from control hw:0

Do you know, what is the log i can see the error cause

Thanks

The error cause isn't logged anywhere. The error message you see shows the cause; the script tries to manipulate a control on the sound card that there is no interface for in the driver.

Do you get the error always or just occasionally in some scripts?

Does the sound card work?

I know that there is an error in some of the scripts:

• Reset_paths.sh
• Record_from_DMIC_and_Headset.sh
• Record_from_Headset_and_SPDIF.sh
• Reset_paths.sh

In those scripts there is a line that says something like

amixer -Dhw:0 cset name='INX Digital Switch' on (or off) where X is the number 1-3.

The INX Digital Switch doesn't exist, and that is what amixer complains about.

You can just remove the offending line from those scripts.

If you get the error many times when running any script, there is a more fundamental error. Possibly a broken sound card, or it isn't attached properly

Hi Ragnar

Thanks for your answer, the real error is the raspberry's version, Initially I'm working with A version, when i change to B version, the use_case_scripts works well, now I don't know how to test the audio play using the lineout jack,  I ran the script Playback_to_Lineout.sh, but when I played the default test of the raspberry hello_audio.bin, It sound by default raspberry's lineout, If you know anything to respect, I'm grateful for your help

EDIT

Executing the test HD Files using the line aplay -Dhw:0 -r 44100 -c 2 -f S32_LE Mozart Ave Verum,flac, the unique I listened is much noise in lineout y headset, Do you know the cause? Thanks

EDIT

You post the answer in this link http://www.element14.com/community/thread/32522/l/no-spdif-out-or-headless-operation  thanks, now I try to do a program sip with PJSUA or run scripts with linkphonecsh, thanks

the raspberry hello_audio.bin, It sound by default raspberry's lineout

The hello_audio program is hard-coded to always use the Raspberry's built-in audio.

I'm working with Raspian 3.12.33+, and I'm having the problem described above:

amixer: Cannot find the given element from control hw:0

is generated on every line executed by "sudo ./Listen_to_LineIn_on_LineOut.sh."

This script works correctly using Raspian 3.10.25_Wolfson+ on the Wolfson audio/PI boards I have (I've tried it on two board sets), so perhaps this is something new?

I noticed that in Raspian 3.10.25+, in ALSA, card 0 is the Wolfson audio card, whereas in 3.12.33+ (I think this is Ragnar Jensen's version--if not, sorry), card 1 is the Wolfson audio card.

When running files like "Listen_to_LineIn_on_Lineout.sh", they work in 3.10.25+, but not in 3.12.33+. 

I get an error message that says:  "amixer: Cannot find the given element from control hw:0".

I'm guessing this difference is how the Wolfson Audio card is mapped to ALSA in the two different distros.

How do I change things in 3.12.33+ to make the scripts work?
