 |
|
A long time ago I used and made an ebuild for a small tool called rcenter. This tool enabled the owners of soundblasters with the remote control (the RM-900 and RM-1000) to remote control their computer / applications. This was all well and good but the program only worked with the OSS drivers which are now depreciated in the 2.6 kernels sooo here is the approach to using the live drive with Alsa and lirc
1. Using either Alsa drivers or those in the kernel compile in alsa support (however you choose) BUT ENSURE that you compile the emu10k1 driver as a module (I have never been able to get this to work with a builting driver
2. Add the following line to the bottom of your make.conf
| Code: | | LIRC_OPTS="--with-driver=livedrive_midi" |
This will ensure that the specific driver gets built with lirc and that you dont have to set this in the future when you update lirc
3. Emerge lirc, in case you didn't already know .....
4. Create a text file in /etc/modules.d/alsa and in that file add the line
| Code: | | options snd-emu10k1 enable_ir=1 |
5. Run modules-update to regen the /etc/modules.conf file
6. Add the snd-emuk101 driver to the modules.autoload as appropriate (the alsa guide and other posts will guide you on this)
7. Change the line in /etc/conf.d/lircd from -d /dev/lirc to nothing
8. (Optional) run rc-update and put lircd into startup
9. (Optional) put lirc into your use flags for extra program support
Thats basically it, but with lirc (as opposed to rcenter) you can also enable and program additional remotes via the irrecord program
If you find you have problems try running lircd -H livedrive_midi -d /dev/midi -n
and change the /dev/midi untill you find the correct one for your setup, if you have to do this you may need to add -d /dev/midiXxX (where XxX is your midi device) to the /etc/conf.d/lirc file
This was tested against a soundblaster-5.1-platinum

Thanks a lot 
I was afraid I could not use my remote until I found this helpful howto
Gentoo has the most wonderful community I've ever seen
Just one thing though:
I thougt point 7 did mean to have a /etc/conf.d/lircd like the following one:
| Code: |
# Options to pass to the lircd process
LIRCD_OPTS=""
|
while it has to be REALLY nothing, meaning:
| Code: |
# Options to pass to the lircd process
#LIRCD_OPTS=""
|
having commented out any line
I then downloaded the correct .conf file for my RM-900 remot from here
I paste it in the post for anyone's convenience:
| Code: |

After install I found only configs for >=RM-1000
now everything works:

Just one small problem remains: at boot time snd-emu10k1 module gets loaded without the enable_ir=1 parameter.
Alsa doen't complain at startup, I just have to shut it down, modprobe the module passing the option and start alsasound again, then everything works just fine.
I'm out of time right now but it seems like an esay thing to fix. I'll look into it tomorrow
