Description Joe Eversole 2003-04-16 11:59:36 UTC 
I have an IBM NetVista with the i845 chipset. I was having problems with ALSA
not playing any sounds dispite not having any error messages and the
installation go without a hitch. But, there were no sounds with anything
(aplay/xmms).

I searched google and found the link I included. someone there said to unmute
the Headphone channel along with Master and PCM. As soon as I issued the amixer
command, I heard a pop on my speakers and aplay started working perfectly.

If the ALSA documentation on gentoo.org contained this information, it would
have saved me a bunch of headaches. :)

please remove me on 'alsa configuration guide'. there are other devs who know more on alsa, i suppose..
Comment 2 Sven Vermeulen (RETIRED) gentoo-dev 2003-06-30 00:24:33 UTC 
Correct me if I am wrong, but this is already mentioned in the docs:

"""
If you got this far, now unmute both Master and PCM channels.

Code listing 3.5

# amixer set Master 100 unmute
# amixer set PCM 100 unmute
"""

Setting this bug as FIXED, REOPEN if needed.
Comment 4 Joe Eversole 2003-06-30 05:32:09 UTC 
No, the current documents do not say to unmute the Headphone channel. Re-read the 2nd paragraph of my original comment and the URL I included for details.

I would flag this for reopening but one cannot apparently reopen their own bug tickets.
