Dear ALSA devels I am writing on an ALSA-related issue that I managed to solve, on Debian testing with kernel 2.6.30 and ALSA 1.0.21. For background and exact symptoms please see these two threads. [1] [2]

The first issue was that there was no sound. I solved it by manually configuring it as follows: debian-liv:/home/liviu# cat /etc/modprobe.d/sound ## ALSA portion alias char-major-116 snd alias snd-card-0 snd-hda-intel alias snd-card-1 snd-usb-audio

## module options should go here options snd-hda-intel index=0 model=hp-dv5 enable_msi=1 options snd-usb-audio index=1

The second issue concerned the external speakers/headphones: when such devices were plugged in, the internal speakers were not muted and the audio stream was not redirected to the external headset (that is, there was no sound in the headphones); although I didn't check, the microphone was probably not working, too. The issue was solved by adding position-fix=1. Thus, the following line was used options snd-hda-intel index=0 model=hp-dv5 enable-msi=1 position-fix=1

I have similar issues on Ubuntu Jackalope, and it seems that on Ubuntu it is quite often that audio cards on HP Pavilions misbehave by default (no sound, no sound in headphones, etc.).

Best regards Liviu
