Hi I added snd-intel8x0m to /etc/hotplug/blacklist but it not works. Still no sound. I got: [root@localhost bednar]# system-config-soundcard Simple mixer control 'PCM',0 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Front Left: Playback 23 [74%] [on] Front Right: Playback 23 [74%] [on] Playing WAVE '/usr/share/system-config-soundcard/sound-sample.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo aplay: pcm_write:1115: write error: Input/output error Darek Borkowski
