so did you try to highlight '1 HDA Creative', press enter, see if you have sound?

it's also possible that after uninstalling pulseaudio, some rogue configuration leftovers.
like /etc/asound.conf - what's the content of that?
you can try to move it out of the way:

Code:

mv /etc/asound.conf /etc/asound.conf.not

the same for ~/.asoundrc.

it just might help, but maybe you have to restart alsa, or reboot if you don't know how to do that.

These can be used by any sound application, these are the devices your VLC can see. Note, to use these nodes the user must be member of audio group. If your system was meant to work with PulseAudio then your user may not be in audio group, you may need to add it.

Thanks; that's very useful.

I checked that I am already in the audio group. (And checked that speakers do work on another system.)

One thing. My /etc/init lists

Code:

4 -rw-r--r-- 1 root  278 May 29  2017 anacron.conf
4 -rw-r--r-- 1 root 2493 Jun  2  2015 networking.conf
4 -rw-r--r-- 1 root  933 Jun  2  2015 network-interface.conf
4 -rw-r--r-- 1 root  530 Jun  2  2015 network-interface-container.conf
4 -rw-r--r-- 1 root 1756 Jun  2  2015 network-interface-security.conf
4 -rw-r--r-- 1 root  337 Jul  5  2017 udev.conf
4 -rw-r--r-- 1 root  360 Jul  5  2017 udevmonitor.conf
4 -rw-r--r-- 1 root  352 Jul  5  2017 udevtrigger.conf
4 -rw-r--r-- 1 root  138 Jan 23  2017 usb-modeswitch-upstart.conf
[/etc/init ]$

so maybe I need to get alsa into this?

A relatively low impact way to diagnose your system might be downloading some live distributions to see if sound works on those. If you find that one of those works, you can take note of the settings and possibly the kernel version and diff them from your own configuration.

Both MX Linux (4.13.13) and Knoppix (4.12.7) are Debian derivatives and both have more up to date kernels than Debian's default 4.9 series.

I wouldn't jump ship from Debian just because the default kernel isn't the latest. You can find kernels up through 4.14.x in backports if it turns out that's what you need.

Yes, but no change.

I did a reboot and then looked for these. I don't have /etc/asound.conf --- in fact no asound files or alsa in /etc

I have got ~/.alsaplayer which contains a config file but this appears to be an uncustomized blank.

Nothing in ~/.local/share/

Good to have checked these though, thanks.

I am getting Knoppix and will see what that produces.
