Problem so zvukom

[Martin Tirsel]

Dobry den,

mam pomerne zavazny problem, mam dosku Asus M2A-VM HDMI s chipsetom AMD 
690G s ALC883 High Definition Audio 6-channel CODEC (HDA Intel 
snd-hda-intel). Pouzivam headsety a ak spravim nahravku z mikrofonu, je 
pocut pomerne rusive pukanie zvuku a okrem toho na vyssich (normalnych) 
hlasitostiach sa prejavuje znacne skrkanie, ako ked nestiha zosilovac. 
Ak sa k tomu prida linphonec, spracovanie zvuku kodekmi, prenos cez voip 
do telekomunikacnej siete, vysledok je taky, ze kvalita zvuku je na 
volanej strane takmer nepouzitelna.

Pukanie sa prejavuje len ak sa do mikrofonu hovori, ak je ticho, vyzera 
to v poriadku, jednoznacne je problem na strane linuxu/driverov, nakolko 
ak na tom samom pocitaci pouzijem windows, zvuk je pekne cisty.

System pouzivam Debian Lenny, skusal som aj live cd Ubuintu 8.04, tam 
ten isty problem, u 8.10 sa mi to nepodarilo overit, Sound recorder sa 
choval podivne a zamrzal. Za kazdu radu budem vdacny, mam tu 10 takychto 
pc konfiguracii, cez ktore sa ma telefonovat a ak to v nasledujucich 
dnoch nespojazdnim, bude trocha problem :(

Pridam este nejake info:
