Have you tried running alsaconf? what happens when you try alsamixer? |
| 56 |
I tend to hate pulseaudio. I fail to see its purpose, the only time i |
| 57 |
tried it gave me a big headache. My (totally biased and personal |
| 58 |
without any techincal background) advice is to stay clear of |
| 59 |
pulseaudio. |
