This was solved today --- turns out the problem is that the Omnibook 800CT/166 exhausts available interrupts with sound, serial, parallel, and irda; when adding a PCMCIA card (NIC) the machine appears to deprive sound of use of it's interrupt. I tried disabling all of these peripherals and re-ran alsa configuration (as 8-bit soundlblaster, although I suspect the ESS driver would be the same outcome). This allowed sound operation to proceed normally. >Message: 2 >Date: Sat, 25 Nov 2006 09:46:03 -0700 >From: "david feldman" <wb0gaz@xxxxxxxxxxx> >Subject: Audio clients block - how to start > troubleshooting? >To: alsa-user@xxxxxxxxxxxxxxxxxxxxx >Cc: wb0gaz@xxxxxxxxxxx >Message-ID: <BAY101-F166D820CEF049048F4709996E00@xxxxxxx> >Content-Type: text/plain; format=flowed > >I'm working on fresh install of the "puppy" linux distribution (version >2.12) on an older machine, a HP Omnibook 800CT.
