I'm not sure if this is what you're wanting to do, but take a look at

Re: no sound no music

My understanding is that the latest raspbian wheezy image includes pulseaudio, and that it is pulseaudio which breaks alsa. I've found that by using the alsamixer control before using the aplay command for the first time after each boot, alsa does seem to play as it did with the previous image. To p...

Re: RPi with Raspbian - can hardly read text

I can hardly read what I'm editing and the experience as a new user is somewhat disappointing, so any idea how I can get legible text? The debian wheezy image has overscan set to re-render everything displayed using just the central area of your monitor screen. Overscan can make what you see appear...

Re: Can I use the armel package qtdmm on armhf raspbian whee

I believe the Raspbian maintainers have a repo on their own, so a check if it is available via apt-get should clear this. Thank you for your guidance. All went well. The apt-get found ... raspbian/wheezy/main qtdmm armhf 0.8.13.3, and it was installed without a problem. From LXPanel I ran the comma...

Re: Can I use the armel package qtdmm on armhf raspbian whee

Did you try to install it via plain apt-get ? Thank you for your reply. I was intending to install qtdmm via apt-get, but then noticed that the packages include armel but not armhf, so I thought I'd ask here first. Should armel packages work on a Pi with armhf raspbian wheezy? Perhaps you could cla...

I'd like to connect my Pi with a digital multimeter, and use the debian package qtdmm to receive, process and display the multimeter readings.

Re: New stable firmware update

The reasons are: - the console is blurred (text looks like upscaled low definition character rendition) - alsa is broken (by pulseaudio)(i.e. speaker-test and aplay no longer work) - the GUI (startx) uses only the center part of the ...

Re: Video thru HDMI jack and audio thru 3.5 audio jack?

You do not say where the sound is comming from. If it is from alsa, then the command:

Code: Select all

amixer cset numid=3 1
will direct audio to the 3.5 mm analog stereo jack.

@Mursili If you can use alsamixer, and aplay /usr/share/sounds/alsa/Front_Center.wav shows no errors, then alsa is probably working for you, and it may be that some of the no sound solutions in the wiki will help achieve an actual sound output. @efflandt I take encouragement from what you say that t...

This is odd since I have used 'apt-get dist-upgrade' and it did not break audio. Do you know whether your audio originates from alsa? Can you still use the alsamixer control? Can you still play a sound file with the aplay command? Can you still control the audio output (i.e. analogue or digital) wi...
