I had the "pleasure" to work on the Inspiron 3500 of my gf today. Same problem as described here with Ubuntu 8.04.1.
However, digging around I got it working. 1.) some mail from these http://www.mail-archive.com/search?q=inspiron 3500&[EMAIL PROTECTED]&start=0 seems to suggest that the Inspiron 3500's NM256 is actually no proper NM256. It seems to be missing AC'97 and use a Crystal chip. 2.) The solution posted here works for me: http://ubuntuforums.org/showthread.php?t=109057&page=3 -- quote -- In file /etc/modules added this line: snd-cs4231 In file /etc/modprobe.d/sound I have: blacklist snd-nm256 blacklist snd-opl3sa2 alias snd-card-0 snd-cs4231 alias sound-slot-0 snd-cs4231 options snd-cs4231 port=0x534 irq=5 dma1=1 dma2=0 -- nm256: no ac97 is found (Dell Inspiron 3500 & others) https://bugs.launchpad.net/bugs/15414 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
