how do i force alsa to reconfigure to new hardware after moving drive to new machine?


a few months back i moved my drive to a new machine. it's slack 13.37. the old machine was a "generic" sempron machine, the "new" one is an HP with a pentium D.

i can no longer capture PCM to various ham radio programs, even though info from alsamixer says PCM is the capture source.

ALSA should have auto-reconfigured. However, you may wish to Google search for AlienBOB's website and then check out the alsaconf script he has there to possibly help.

I would try, as root, deleting /var/lib/alsa/asound.state and then running 'alsactl store'. It might be best to reboot after doing this.

sorry... didn't work.... i'd hate to have to resort to running cables between the headphone output and the line input, but i guess that's what i have to do to get this to work
it seems that the capture input even though it's reported as this:
Code:
00-00: ALC888 Analog : ALC888 Analog : playback 1 : capture 1
00-02: ALC888 Analog : ALC888 Analog : capture 1
must be something ekse

Possibly this:

alsamixer
alsactl store

results from "cat /proc/asound.pcm same as in post #4 ..... .asoundrc, /etc/asoundrc.conf, /etc/modprobe.d/sound.conf files do not exist....

this seems to be a limitation of the audio hardware, but i'm not absolutely sure of that yet.... i'm thinking i might just get a "real" sound card, and that might have more internal signal routing options... the problem with hardware built in to the motherboard, is that it was designed in a hurry (or to give minimal functionality at a low price point), and doesn't have the same features a well thought out sound card would have.... i.e you can get a volkswagen for free, but the porsche will cost you quite a bit more..... (or for those of us in the US, you can get a Suburban for next to nothing, but the Cadillac built on the same chassis will cost as much as a house)

I have had problems over the years recording from the PCM device in Alsa. On my old laptop, I could get it to record in Windows, but the Linux driver just wouldn't show the PCM (or other corresponding) device for me to record internal sound. I tried all sort of things suggested on the net, and even all the variations/models of that sound card using the modprobe.d - but in the end I couldn't find one which would allow me to record internal sound under Linux. My new laptop looks a bit more promising as it at least shows a PCM device, but I have been unsuccessful so far getting Audacity to capture from it.

I'm not sure if this will contribute to the discussion but after reading this thread I just checked mixer settings and noticed PCM gone. The only change I can remember between a fresh install and current setup is I now use a generic kernel instead of the huge one. Are we missing a module?

I believe the pcm channel only shows up in the mixer for certain card models and for certain drivers. If the kernel module thinks your card doesn't have that capability, or your card really doesn't have that capability, pcm won't show up in alsamixer. I believe that is why the usual advice is to try a number of models in the module configuration (under /etc/modprobe.d) in case there is some variant of your card/sound chipset which supports pcm.

@jj25vm: I guess so. I only wanted to say HUGE kernel did think the card had that functionality whereas module loaded by generic did not. So rebooting w/ huge and checking may shed some light to the problem. Personally I do not care whether PCM shows up or not, I'm not doing anything with it. I will check modprobe.d, though.

A pity the quick and dirty did not work.

Please also supply the exact model of your HP computer.
