Known problem with the TP600E. The soundcard is incorrectly identified as CS462x.
There are plenty of web pages out there describing solutions to this. But here is the Reader's Digest version: 1. Blacklist the incorrect sound card in /etc/modprobe.dblacklist. Add lines for blacklist snd-cs46xx blacklist cs46xx as written above - with the xx's 2. Add the following lines into /etc/modprobe.d/alsa-base alias char-major-116 snd alias char-major-14 soundcore alias snd-card-0 snd-cs4236 options snd-cs4236 isapnp=0 cport=0x538 port=0x530 sb_port=0x220 fm_port=0x388 irq=5 dma1=1 dma2=0 alias sound-slot-0 snd-card-0 alias sound-slot-1 snd-card-1 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss alias /dev/mixer snd-mixer-oss alias /dev/dsp snd-pcm-oss alias /dev/midi snd-seq-oss options snd cards_limit=1 NOTE: When copying and pasting the above, make sure that the line starting with 'options...' is *one* line ending with '...dma2=0'. 3. Add the line snd-cs4236 to the file /etc/modules Reboot. Also important: During power up, if you press F2 (I think), you get into change the config. In this you need to make sure that the Fastboot option is *disabled*. If you are still having no success: try adding 'acpi=off pnpbois=off' at the end of the kernel boot params. Press 'esc' during Grub countdown and select 'e' to edit the boot command and add these to the end. If need these to allow my Xircom PCMCIA ether card to work. One last thing: the default starting volume is very low, so make sure that you set the volume to high using the keyboard Fn+PgUp key combination. -- Thinkpad 600e sound hardware not detected with Ubuntu "Dapper Drake" live CD (Flight 6) https://launchpad.net/bugs/40116 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
