Description Peter Humphrey 2004-09-04 12:46:04 UTC 
My system refuses to make a sound under Gentoo, though it's fine with SuSE 9.1 and Windows XP. When I had CONFIG_SND_VIA82XX=m, alsa couldn't find the sound card at boot time (yes, I did have snd-via82xx in /etc/modules.autoload.d/kernel-2.6 and had run modules-update). Setting CONFIG_SND_VIA82XX=y enabled alsa to find the card ok, but KDE sound test gives only silence. At the time I had verbose printk and debug kernel options set, as recommended in /usr/src/linux/Documentation/sound/alsa/ALSA-Configuration.txt. This gave only one extra clue, which was a wrong-pointer error shown by dmesg: 
"ALSA sound/pci/via82xx.c:737: invalid via82xx_cur_ptr, using last valid pointer"
This came up 8 times after pressing the Test button once in the KDE sound configuration panel.

I'm mystified.


Reproducible: Always
Steps to Reproduce:
1. Open KDE sound system configuration panel.
2. Press the Test button.
3. Listen for output.

Actual Results:  
Silence.

Expected Results:  
A sound. Any sound!

Ok, so I needed alsamixer installed. Apologies to all concerned.

I'm considering reopening this as a documentation fault.
