As soon as an application inside OS X 10.4 tries to access the audio devices (both input and output) MOL locks up/crashes. This what it prints before locking up: ***** SIGNAL 11 [Segmentation fault] in thread main-thread ***** si_signo = 11, si_errno 0, si_code 00000001, si_addr 0x3e4f0000 Last RVEC: 0x0 (0), last OSI: 36, mac_nip 150E04A0 NIP 0x0fbc4364 ***** Backtrace ***** 7f9d6430: signal_handler + 0xf0 7f9d6450: 0x7f9d67a8 7f9d6aa0: 0x00000e03 7f9d6ab0: 0x0ff4aa40 7f9d6ad0: 0x0ff4dcc0 7f9d6b00: 0x0ff4e054 7f9d6b60: 0x0ff6022c 7f9d6b90: 0x0ff53154 7f9d6bd0: 0x0ff6054c 7f9d6c20: 0x0ff4b0b0 7f9d6c30: alsa_open + 0x234 7f9d6e70: start_sound + 0xfc 7f9d6e90: osip_sound_cntl + 0x324 7f9d6ec0: rvec_osi_syscall + 0x84 7f9d6ee0: do_rvec_jump + 0x3c 7f9d7090: mainloop_start + 0x98 7f9d70b0: main + 0x508 7f9d7290: 0x0fb66930 7f9d74a0: 0x0fb66a78 7f9d74b0: 0x00000000 cleaning up...

(In reply to comment #4) > emerge --info (this is better than IM ;) LOL ;=)
It looks like you're running on a G3. Are you sure you disabled altivec? It's in /etc/mol/molrc.osx. Also, audio input shouldn't work atm, but I can't reproduce this for audio output.
Yes, Altivec support is disabled. $ cat /etc/mol/molrc.osx | grep altivec disable_altivec: yes
Can you try with OSS output instead? (Use ALSA's OSS emulation). Are you sure there's no version mismatch between the alsa driver you're using and the ALSA library version? Is this any sound or a certain application? Is there another application blocking the sound device?
Please reopen the bug when you've tested with my suggestions in the previous post. Thanks!
No response. Feel free to reopen if you can reproduce it.
