Re-posting... sorry I hijacked a thread. I have an hp pavilion 713a machine, with Microstar MS-6577 Motherboard. This has an Avance AC97 audio chip on board, which works fine under the pre-loaded XP. I'm trying to migrate it to Mandrake (10.0 Community), and running into the odd obstacle or two... Firstly, the drivers themselves. "Configure your computer" says the hardware itself is working fine (there are no error messages). I've tried using the alternate drivers as listed here, but with no better success than the default (snd_intel 8x0). The diagnostic procedures tell me to run a series of commands, and I've done these, but the results are cryptic: chkconfig --list sound reports a series of 0: .. 6:, with off or on. chkconfig --list alsa does the same. What do these mean?
Frans Ketelaars replied: >See 'man chkconfig'. In this case it lists the runlevels in which a >service like sound or alsa is started. Posting the output of the >diagnostic procedures is always a good idea. Nextly, the mixer. I'm using KDE desktop, so up comes Kmix. The help files for this tell me nothing about what the red and green buttons (above and below the sliders) are for - can ANYONE tell me? Also, I can see a "Mix Mono" output, but after having fiddled the drivers the stereo one has disappeared - is this a symptom of the lack of sound out? Yes, I can right-click the slider and split the control, but the right one snaps to the left setting, so that doesn't turn it into stereo, it's really a mono one.

Do applications 'appear' to play? > To continue the saga: I tried alsamixer, but with no more success in terms of sound output, and though it explained the red and green buttons in Kmix it raised a few points in itself. Kmix (bottom right corner) shows I am controlling Intel 82801DB-ICH4. I presume this is correct for the AC'97 as embedded on the mobo. The MCC (under Hardware/Hardware) says the Soundcard is ICH4 845G/GL Chipset AC'97 Audio Controller, and Module is snd-intel8x0. The green buttons are muted when dim, and un-muted when bright, i.e enabled. The red buttons are "capture selected" when bright. alsamixer says Card: Intel 82801DB-ICH4, and Chip: Realtek ALC202 rev 0. The onboard LAN is a Realtek RTL8139 - is this part of the same chip? I'm having troubles with that too... man alsamixer says Spacebar toggles Capture mode on a valid input, adding or removing it from the capture sources. Its behaviour belies this: it selects that channel for capture, removing all other inputs from capture sources. Having found this, I noted that Kmix seems to allow multiple sources fro capture, though the red buttons will not clear immediately after being selected: another source has to be toggled in between. Strange... With a CD in the drive, and the CD player indicating that it is there and playing a track, and with the mixer (either alsamixer or Kmix) showing CD selected and volume high (80%+), there is still no sound out. #chkconfig --list sound sound 0:off 1:off 2:on 3:on 4:on 5:on 6:off #chkconfig --list alsa alsa 0:off 1:off 2:on 3:on 4:on 5:on 6:off #runlevel N 5 Any takers? :-) Hopefully...
