after my sound was broken again i did this:
remove all other files beginning with sound in /etc/modprobe.d/ only keep sound.conf edit sound.conf so it looks like this root@slack64:~# more /etc/modprobe.d/sound.conf alias sound-slot-0 snd-hda-intel options snd-hda-intel index=0 id=default reboot and all is fine hopefully :) |
ok, so tonight none of this helped. i guess i didn't check the website google sent me to when i searched for "64bit flash for linux". somehow i accidentally downloaded the 32bit version.
If your flash plugin doesn't show on about:plugins, and nothing seems to work, run: "file ~/.mozilla/plugins/libflashplayer.so" If it returns "32bit executable", etc, you got the wrong version if you're on Slackware64 (and visa versa). PEBKAC |
Flash for 64 bit linux is trash. To get decent flash on 64 bit Slack, I installed the multilib files and then installed 32 bit browsers (Firefox and google chrome from slackbuilds--the 32 bit chrome now comes with it's own flash plugin).
Nothing else that I tried really worked. |

SB Live working again
Thanks for the blacklist idea.
Sound was working fine, then one reboot and the HDMI sound onboard soundcard took precedence over the other modules. A quick way to remove snd modules without rebooting: lsmod|awk '/snd/{print "modprobe -r "$1}'|sh Run it a few times, it will unload modules as they no longer have any deps. I use XFCE, so I needed to remove the Mixer app from the panel to free the binding for the Intel sound driver. Then I ran the above again and it removed the remaining modules. Then I updated /etc/modprobe.d/blacklist.conf added: blacklist snd_hda_codec_atihdmi blacklist snd_hda_intel Then I reran alsaconf - Bingo! I readded the mixer to the panel and it now picked up SB Live mixer. mpg321 now worked fine and sound was all back. cat /proc/asound/oss/sndstat Sound Driver:3.8.1a-980706 (ALSA v1.0.21 emulation code) Kernel: Linux mars 2.6.33.4-smp #2 SMP Wed May 12 22:47:36 CDT 2010 i686 Config options: 0 Installed drivers: Type 10: ALSA emulation Card config: SB Live! 5.1 (rev.7, serial:0x80641102) at 0xe800, irq 20 Thanks for the tip.
