Emerge alsa-utils and turn up the volume and it always works for me. Maybe there's a different reason for ALSA_CARDS than I understand. I know the x11 "VIDEO_CARDS" setting helps not only X, but other programs too, decide which hardware to support. The same may be true of ALSA_CARDS. I would think though, that this would be most important for people using the ALSA-supplied drivers, as in-kernel drivers are selected at kernel configuration time and alsa-provided drivers must use another way to specify which sound hardware to support. -- gentoo-user@gentoo.org mailing list
