Linux ALSA driver
- This device is supported by the alsa driver since 1.0.15 (including R61/T61/X61 bugfix)
- This device is supported by the kernel since 2.6.23 (which includes alsa 1.0.15 !)
For previous versions
However, Takashi Iwai has added support to this device in Alsa development version ... Still have to wait to get it included in the Linux Kernel... Note: It is rather trivial to get this working in a standard kernel right now, It is only 3 patches on top of the stock 1.0.14 code:
Alsa-Driver 1.0.14 added some support for this chip, but did not work on my T61; however, using the latest HG/Mercurial makes everything work. I created a Debian package for unstable/sid with the HG alsa that works for me, available at . --Jello 15:31, 6 July 2007 (UTC)
amd64 debian package here: http://www.cse.unsw.edu.au/~jdas417/alsa-modules-2.6.22-1-amd64_1.0.14-1_jda+2.6.22-3_amd64.deb --jashar
Works with Kernel 2.6.22 and Alsa 1.0.14a --Schlodty 12:01, 21 July 2007 (UTC)
Did not get it to work on X61s with either of the above packages. Newer HG packages do support this chip, so alsa 1.0.15 should have full support for this chip. --hjh 9:09, 27 July 2007 (UTC)
Works with a patched 220.127.116.11 kernel using the 2007/07/20 patch from ftp://ftp.alsa-project.org/pub/kernel-patches/ . Just make sure that you have the PCM channel unmuted and the speaker switch checked. --Mozz 17:13, 7 August 2007 (UTC)
Above patches are in kernel mainline from Kernel 2.6.23-rc1 , it works on my T61 --Brain79 22:01, 09 August 2007 (UTC)
Worked on my T61 running Debian Lenny, with a sid 2.6.23 kernel. (That is, I installed Lenny (and so have a Lenny version of ALSA - 1.0.14, and then upgraded the kernel to 2.6.23 from the sid repositories). Kyle Barbour 09:46, 13 February 2008 (CET)
Not working with 18.104.22.168 and alsa 1.0.16 on T61 --Linea 23 March 2008
The reason modem must be enabled (at least on the x60,x61 series) is because the modem and sound share a bus. (got that from calling lenovo hardware support today) Aliencam 01:43, 28 January 2008 (CET)
Remember the hardware mute on (some?) Thinkpads, including (at least some) Thinkpad T61s. If you don't have sound and all the requisite modules, versions, etc. are loaded and up-to-date, try pressing the physical volume up button a few times on your keyboard to turn it off.
