No output sound at all but mic is working

Hi there, i need some help here.
trying to get this working since some days now.
it appeared across all distributions i tried. regata fedora …
while everything seems ok, no output.
i tried some things found in various forum across linux, but nothing helps.
alsamixer is working fine, i unmuted everything.
i hope u can give some hints how to handle this problem.

Just an hypothesis but, I see that you have two sound cards could this be the cause of issue? perhaps a race condition is occurring and hence neither card is getting the sound to output. Try to set a default sound card with the below archwiki article. Test both cards alternatively.

Would also suggest looking at this post and the one’s below it,

the 2nd is the nvidia hdmi device.
but i solved it finally.
i unmuted all but didnt noticed the small MM in the alsamixer. which can be turned on by hitting “m”.
it wasnt seen in any of the options in soundpanel.
thx to your link i was able to find the most simple solution thx :slight_smile:
