I'm running Debian 10 on my laptop.

I tried to install a driver for the realtek alc665 sound card. I failed and as the result I don't have sound on my system.I can play songs but I can't hear anything though volume control is available and HIGH.

When I run pavucontrol audio mixer comes up and in the configuration tab I see: no cards available for configuration In the output devices tab I see dummy output

I opened up a terminal and this is the output from lspci -v: (Only audio devices in this list)

The output form lshw -c multimedia might also be usefull:

When I ran alsa –version , I got this:

ALSA lib confmisc.c:767:(parse_card) cannot find card '0'
ALSA lib conf.c:4568:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory

aplay: main:828: audio open error: No such file or directory

and finally this is the output from aplay -l:

aplay: device_list:272: no soundcards found...

It seems that drivers are currently available but not for pulseaudio. So how could I fix this?

I got this error because I recently installed TiMidity++ (to get sound with Linthesia) and it was started automatically at boot time.

Maybe it will not fix your issue but to get sound through PulseAudio again, I had to stop the TiMidity++ service, for example if your Linux distribution is using Systemd, you can use the command systemctl stop timidity to stop the service and systemctl disable timidity to disable the service automatic startup.
