Hello Nigel, Thank you very much for your time helping me with this. Model Number from the sticker underneath the machine is: MIM 2300 Notebook PC. I tried the different probe-mask=?. Probe-mask=1 works OK but not the others. model=lenovo-ms7195-dig doesn't work. Kmix shows varying channels depending on the 'model' or 'probe-mask' used. probe-mask=1 gives the most channels. alsamixer now loads up OK but still no sound. Shows as ALC883 with 'probe-mask=1' Starting Amarok elicits the xine error dialogue window with "xine was unable to initialize any audio drivers" UPDATE: With 'probe-mask=1 and using Rhythmbox I can get sound out of the speakers and the front headphone jack. Volume not very high out of the speakers but is good from the headphones. Too much system activity or keyboard activity (I'm writing this listening to Tchaikovsky and I can hear interruptions from the keyboard at times) seems to interfere with the audio stream. Also there is a lot of noise from the CD drive coming through the earphones. Don't know how that is happening. Pulseaudio Vol Cntl can be used as can the panel Vol. Cntl. and also alsamixer. It is not properly fixed yet, not anywhere near as good as the sound under Vista, but it is very, very close and is usable with the headphones. Perhaps the next driver update will fix it. A thought, pulseaudio is the default audio driver for Fedora 9 and trying to remove it brings up a plethora of dependencies that rely on it. Perhaps there is some conflict between ALSA and pulseaudio. Your help has been indispensable and I cannot thank you enough for all the time you have put in. Thank you again. -- Kind regards, Graeme Nichols. ...
