Hi,

Does anyone know how to fix alsamixer output in Yocto?

It has been broken for a long time. Please see the attached picture.

Any ideas?

Thanks,

Fabio Estevam

From the alsamixer manpage:

And, yes, from my experience, plain old xterm seems to work fine.

I am using minicom.

alsamixer works fine with a LTIB based rootfs in this same terminal.

It can be related to missing terminal info or even changes on the
version. But which terminal are you using? I use rxvt-unicode.

I use minicom, which reports "Terminal emulation : VT102".

I have been using screen to serial console for a while, so I did not
try minicom for ages.

Tried 'screen' and it allows me to use alsamixer. Would still be nice
to have it working under minicom though.

Thanks

Ok but someone which uses it needs to figure what is missing. It
proves it is related to terminal info so maybe you can research for
it.

How are you connecting to your board?  I've seen this when using
minicom directly to the serial port but the output is much better
(correct) if I connect to the board using ssh (and hence the rendering
is happening on the connecting host and not the board).  I'd like to
see it fixed as well, but for now I just use ssh.

Yes, there should be a way to fix this, as I have tried alsamixer with
minicom on both LTIB and Buildroot rootfs and it works fine there.

Should we report this to the person that packages alsa-utils in Yocto?
Does anyone know who that person is?

Thanks
