Hi, I have a two year old Thinkpad T510 with a Conexant CX20585 sound chip which has recently developed a habit of turning the speaker off at random. The power state of node 0x1f changes from 0x00 to 0x33. Resetting it with hda-verb or suspending to RAM ( closing/opening the lid ) "fixes" the problem . I know this topic has been discussed before on this list but I'm unsure of whether it was ever resolved ( beyond running a script that resets the state ) or wether it is really a hardware problem ( overheating ? ) It seems to happen at any volume setting and it seems to happen whether the sound card is in use or not. peter ------------------------------------------------------------------------------ Minimize network downtime and maximize team effectiveness.
