I made a custom ~/.asoundrc on Ubuntu 24.04, but when I run alsamixer I get an error:
ALSA lib conf.c:4123:(config_file_open) cannot access file /home/ruslan/.asoundrc
ALSA lib conf.c:4043:(snd_config_hooks_call) function snd_config_hook_load returned error: Permission denied
ALSA lib conf.c:4650:(snd_config_update_r) hooks failed, removing configuration
cannot open mixer: Permission denied
Trying to figure out what's going on, I tried strace on it:
$ strace -y alsamixer |& grep -B9999 EACCES

So the program is trying to open the file, getting a "Permission denied" error. But the file is accessible:
$ cat /home/ruslan/.asoundrc
pcm.!default {
type hw
card 2
}
$ lsattr /home/ruslan/.asoundrc
--------------e------- /home/ruslan/.asoundrc
Also, alsamixer doesn't appear to have any weird properties like setuid or anything:
$ type alsamixer
alsamixer is /usr/bin/alsamixer
$ ls -lh /usr/bin/alsamixer
-rwxr-xr-x 1 root root 101K Feb 11 2025 /usr/bin/alsamixer
And stopping the program at the __fopen_internal of the file being opened (just in case something locks the file by this point of execution) still lets me cat it as shown above.
So what could be happening here? Why does opening for reading of a perfectly accessible file result in a "Permission denied" error?
