Value (OEM) of around June 1999. >Description: When playing back any mono audio, there is a lot of "noise" (usually crackles and pops!) No such distortion is noticed when playing stereo sound. Judging by feedback on the mailing lists, this problem is not limited to the Soundblaster Live! Value card but a range of SBLive! cards, all of which use the newpcm/emu10k1 driver. The card functions normally in other operating systems that support it. >How-To-Repeat: I tested this with a considerable number of stereo and mono WAV files and MP3 files, using 'play' and 'amp' respectively. The sound quality of the stereo files was as expected, but the mono audio output was distorted. The same files have been tested under other operating systems that support it, and this problem did not occur, which leads me to believe that it's a driver problem. >Fix: No (yet), sorry! >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
