New soundcard: jitter problems
Hi,
I tried to solve the problem of rather crappy sound on my workhorse PC, so I bought a low-profile PCI soundcard: Code:
$ /sbin/lspci | grep -i audio Code:
# echo "blacklist snd_hda_intel" > /lib/modprobe.d/onboard-sound.conf Now what can I do to get rid of that? |
Could you try go to audacious settings->plugins->effects-> select sample rate converter and click its settings button and in dialog window there enter "48000" in every box. Additionally, select "linear interpolator" at bottom for lowest cpu usage. This helped me with my onboard soundcard (since it only supports 48000 Hz sampling frequency).

software mixer isn't necessary but I like to customized my software mixer, you can adjust your rates in there. When I mixed up 32 bits drivers with 64 bits libraries, then my wine only had crappy sound. |
me thinks the term for what you experiencing is sound skipping, not jitter. Sound skipping is caused by latencies, jitter refers to the variance of the latter.
if you feel game you can try a cpu scheduler designed for desktop work and low latency (bfs). Maybe you need to tweak some process priorities on top of that. |

For the record, I had the exact same problem as you. My solution was to buy a new soundcard. I bought a Soundblaster Audigy SE (was only about $25).
But I had problems with other applications as well (Audacity and Flash video, in particular) so for me an Audacious-only solution wouldn't be enough. Are you not having the hiccup issue with other apps too? |
