I use the kernel drivers exclusively, and never set ALSA_CARDS or |
35 |
anything else for that matter. Emerge alsa-utils and turn up the |
36 |
volume and it always works for me. Maybe there's a different reason |
37 |
for ALSA_CARDS than I understand. I know the x11 "VIDEO_CARDS" setting |
38 |
helps not only X, but other programs too, decide which hardware to |
39 |
support. The same may be true of ALSA_CARDS. I would think though, |
40 |
that this would be most important for people using the ALSA-supplied |
41 |
drivers, as in-kernel drivers are selected at kernel configuration |
42 |
time and alsa-provided drivers must use another way to specify which |
43 |
sound hardware to support. |
