No sound - Slack 12.2, HP 6730s
I've installed Slack 12.2 (all packages for simplicity) onto a HP 6730s laptop with an integrated Intel HD audio in it. I have no sound. I've tried some tricks without any success. E.g. I've reinstalled a/devs-xxx.tgz in order to have /dev/dsp0 etc. After I had reinstalled the package I had /dev/dsp0, /dev/dsp as a symlink etc. There were no sound at all. After a reboot I noticed that the reinstalled devices disappeared. (!???)
lsmod says that there are a large number of snd modules are loaded:
snd snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd _mixer_oss,snd_hda_intel,snd_pcm,snd_timer,snd_hwd ep
Alsaconf, alsactl etc. seems to work correrctly, Master, Headphone, PCM is not muted.
Neiter aplay nor mpg123 can produce a hearable sound.
What should (can) I do? Thx, KEA.
