Any way to get the sound working on this laptop. DSL runs fine, just so sound output

Hmm.. Maybe it is just a Sounblaster compatible card.Try opening an terminal window and type: sudo su modprobe sb exit exit and then try XMMS to play a song. Posted by Borderpatrol on Mar. 15 2006,07:01
I tried that and when I went to play a song, it took 5 realtime seconds to play one second of the song and was rather choppy. Any suggestions?

You might need to specify a dma address for your sound card, like this:

That command worked. Thanks.Do I need to do this everytime or will it store it, or do I have to edit a file? Thanks Edit: The laptop plays CD's fine, but when I play a MP3 off of my hard drive which is mounted /dev/sda2 it is choppy. What can i do to fix. This is be used for DJing and I cant copy MP3s to my laptop hdd Posted by cbagger01 on Mar. 16 2006,03:47
You can add that line to your /opt/bootlocal.sh file.You can edit it by Right-clicking on the Beaver desktop icon and choose "Beaver as super user". Don't add the "sudo su" line, just the one that starts with modprobe Not sure about the choppy play on your /dev/sda2 drive. Maybe your USB controller is using the same interrupt as your sound card? I suppose you could copy the mp3 files into your ram disk (/home/dsl) and then play them from there. Posted by Borderpatrol on Mar. 16 2006,07:13
I would copy them over to the HDD but I dont have the space for the amount of files that I would be playing. How do I change the interupt to see if that works?

I have a theory on the sound. I had to add the USB HDD to fstab manualy then create the folders in /mnt myself. I cant open them as DSL but as root. How can I fix that so that dsl can open them and that should fix the problem. I hope...

Further analyisis(sp?) reveals that it has trouble decoding MP3s, OGG, etc. I copied a MP3 over to the HDD and had the same problem.

Your sound problem most likely has to do with IRQ or DMA settings. Before version 2.2 for my sound I used SB pro irq=7 dma=0. other settings for SB would produce the choppy sound you are experiencing. After I installed 2.2 those settings would not work. I am now using regular SB irq=5 dma=1 any other setting produces choppy sound. Try some different options and see what happens.

I checked and the numbers i was entering for the DMA and IRQ was correct, however, when I changed CD playback from analog to digital auto extraction, I had the same problem.
