Hi David,
I have attached a zip file containing three output files from the alsa-info script for Acer 4930.
1. output from 10.04 with sound
2. output from 10.10 without sound
3. output from 10.10 with sound : after adding 'options snd-hda-intel model=auto' in alsa-base.conf
After adding model=auto in 10.10, I have verified that the internal speakers, headphone output and internal microphone work fine.
I cant verify line-in, HDMI out etc. as I don't have the required accessories right right now.
Some other observations:
1) As mentioned in comment#23 of Bug #617647 ,
alsamixer reports a different chip in 10.10 vs. 10.04.
10.10 Card: HDA Intel Chip: Intel Cantiga HDMI (Sound doesn't work)
10.04 Card: HDA Intel Chip: Intel G45 (Sound works)
2) Sound preferences --> Hardware --> Profile
10.10 : shows analog Stereo, digital stereo input and output, 5.1 Channel Surround output
10.10 (with model=auto) : shows analog Stereo, digital stereo input and output
10.04 : shows analog Stereo, digital stereo input and output
Let me know if you need any further information.
